  • Angular momentum effects on the decay modes of hot compound nuclei formed
           in [math]Kr+[math]Ba reactions

    • Free pre-print version: Loading...

      Authors: Dalip Singh Verma, Kushmakshi, Pooja Chauhan, Vivek
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      The dependence of decay modes of hot compound nuclei formed in [math]Kr[math]Ba reactions on the angular momentum has been analyzed using the dynamical cluster-decay model. This has been done by analyzing the change of fragmentation potential, preformation probability, penetrability and cross-section as a function of the fragment mass number at various values of the angular momentum. The evaporation residue cross-section calculated using dynamical cluster-decay model has been compared with the measured one for the channels: [math], [math], [math] for the decay of [math]U[math] and [math] for [math]U[math]. The summed up fragment cross-sections for the light particles, intermediate mass fragments and fission fragments as a function of angular momentum have been studied which gives an idea for the change of reaction mechanism with angular momentum. The charge distribution of the fission fragment cross-section shows an odd–even staggering, i.e., the probability of even-Z fission fragments is relatively higher than others. The mass distributions obtained within the dynamical cluster-decay model for the decay of [math]U[math] are in conformity with mass distributions determined by means of the double kinetic-energy technique in literature. The position of the most probable channel has been found to be fixed to a constant atomic number instead of mass number.

  • Conformable fractional Bohr Hamiltonian with a four inverse power terms
           potential for triaxial nuclei

    • Free pre-print version: Loading...

      Authors: K. Ahmadou, A. Atangana Likéné, J. M. Ema’a Ema’a, C. N. Takembo, P. Ele Abiama, G. H. Ben-Bolie
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      In this paper, we look for a novel analytical solution of the Conformable Fractional Bohr Hamiltonian in the presence of a four inverse power terms potential in [math]-part of the collective nuclear potential. The new expression for the wave functions and energy spectra is obtained using the conformable fractional extended Nikiforov–Uvarov method. The effect of the conformable fractional formulation is studied on root mean square deviation, and normalized fractional eigen energies of ground state band, [math]-band and [math]-band of [math]Pt, [math]Pt and [math]Pt atomic nuclei. The [math] transition rates are calculated within the fractional domain. We compare our results with the experimental data, the classical Bohr Hamiltonian model with four inverse power terms potential, and other relevant theoretical works. We discuss on how the fractional parameter [math] acts on the spectra of triaxial nuclei. The results provided by our new approach are found to be in good agreement with the experimental data and improved compared to previous works.

  • Constraining the axion mass from the nonobservation of [math] decay

    • Free pre-print version: Loading...

      Authors: A. V. Penacchioni, O. Civitarese
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      In this paper, we study the interaction of neutrinos with nonrelativistic axions. Axions are low-mass neutral bosons whose existence has been proposed long ago by Peccei and Quinn to explain the spontaneous breaking of the CP symmetry in the early Universe. We treat them as pseudoscalar particles, which could be one of the constituents of cold DM. The interactions between axions and neutrinos might be a possible mechanism to explain for nonzero neutrino masses. Here on, we present an analysis which combines the limits for the neutrino masses extracted from the nonobservation of the neutrinoless double beta ([math]) decay with the ones corresponding to the coupling between axions and neutrinos. We begin by defining the neutrino–axion interactions, then we extract the values of both the axion and neutrino masses by taking from the literature representative values of the strength of the couplings and of the matrix elements of the operators participating in the currents.

  • Emission characteristics of the target fragments at relativistic energy

    • Free pre-print version: Loading...

      Authors: M. K. Singh, S. Karmakar, V. Singh
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      In this recent work, we present the characteristic of the emission of the black particles ejected with [math] [math] [math] and [math] [math][math] i.e., in the forward and backward hemispheres, respectively. For the multiplicity variation study of black particles, we have considered the interaction of [math]Kr beam with the CNO, AgBr target present in the nuclear emulsion detector. After doing the analysis of the data, we have found that the emission possibility of black particle is greater in the forward hemisphere (FHS) angle whereas in the backward hemisphere (BHS) angle, it is quite low. Along with this, we have also found that the emission probability of black particles does not posses any relation with projectile mass as well as with the incident energy. In this work, we have also studied the characteristics of shower and et al. particles using a new parameter Q (total charge [math] of the outgoing projectile fragments emitted in forward cone [math], here Z denotes charge, and PF denotes Projectile Fragment) instead of impact parameter to distinguish the different type of collision for two interacting nuclei. The observation from this study suggests that the emission probability of the shower particles as well as gray particles increase as the value of Q decreasing (i.e., as we move from peripheral to central colisions). The results of this work are also compared with the context of other experimental observations and it seems to be relevant.

  • A bag model of matter condensed by the strong interaction

    • Free pre-print version: Loading...

      Authors: Zhi-Qiang Miao, Cheng-Jun Xia, Xiao-Yu Lai, Toshiki Maruyama, Ren-Xin Xu, En-Ping Zhou
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      Inspired by various astrophysical phenomenons, it is suggested that pulsar-like compact stars are comprised entirely of strangeons (quark-clusters with three-light-flavor symmetry) and a small amount of electrons. In order to better constrain the properties of strangeon stars, we propose a linked bag model to describe the condensed matter by the strong interaction (i.e., strong condensed matter) in both 2-flavored (nucleons) and 3-flavored (hyperons, strangeons, etc.) scenarios. The model parameters are calibrated to reproduce the saturation properties of nuclear matter, which are later applied to hyperon matter and strangeon matter. Compared with baryon matter, the derived energy per baryon of strangeon matter is reduced if the strangeon carries a large number of valence quarks, which stiffens the equation of state and consequently increases the maximum mass of strangeon stars. In a large parameter space, the maximum mass and tidal deformability of strangeon stars predicted by the linked bag model are consistent with the current astrophysical constraints. It is found that the maximum mass of strangeon stars can be as large as [math], while the tidal deformability of a [math] strangeon star lies in the range of [math].

      Authors: K. Prathapan, M. K. Preethi Rajan, R. K. Biju
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      The decay characteristics of various clusters and neutron halo nuclei from heavy elements [math] are studied within the framework of the Coulomb and Proximity Potential Model for Deformed Nuclei (CPPMDN) and using a new empirical formula proposed by us. The predictive power of our formula is verified by comparing the predictions with the available experimental data and with the predictions of other models such as CPPM, Universal Decay Law of Qi et al. (UDL), Unified Description formula (UD) of Ni et al. Using the present formula and CPPMDN, decay half-lives of various light clusters from heavy elements are calculated, and the results are compared with the predictions of UDL, UD, and predictions made by Santhosh et al. based on the Modified Generalized Liquid Drop Model (MGLDM). The decay half-lives of halo nuclei from heavy elements are also calculated using the new formula and CPPMDN and compared with the predictions of UDL, UD, and the predictions made by Santhosh et al. based on the Coulomb and Proximity Potential Model (CPPM).

  • Relativistic and nonrelativistic mean field analysis of the shell
           evolution in [math] Ar isotopes

      Authors: Hussam A. Bahr, Ali A. Alzubadi
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      The systematic search of axial ground state and the emergence of new gaps in neutron-rich [math]Ar isotopes are the challenging of current calculations of relativistic and nonrelativistic mean field models. For this purpose, we have employed the model based on Relativistic Hartree–Bogoliubov (RHB) with the density-dependent effective interaction of point coupling DD-PCX type. However, the nonrelativistic mean field calculations based on Hartree-Fock model were carried out with Skyrme SV-min parametrization. All the present calculations were performed within axial symmetries. The results provide that most of isotopes show an oblate-deformed ground state. In particular, [math]Ar and [math]Ar display a spherical shape in their ground states with SV-Min calculations. There is a notable signature of the sub-shell closure at neutron number [math], whereas [math] is expected to be nearly quenched in the spherical ground. Furthermore, coexistence features are predicted in the neutron-rich [math]Ar isotope. We have also studied the neutron axial densities and its central depletion in the well-deformed grounds for the first time. In addition to these, the proton single-particle evolution and bubble-like structure at [math]Ar are very well reproduced with DD-PCX calculations.

      Abstract: International Journal of Modern Physics E, Ahead of Print.
      The elastic and inelastic scatterings of deuterons from [math]C are registered in a wide range of angles at the laboratory energy of 14.5[math]MeV. Data on the differential cross-sections are treated within both the optical model and coupled-channels method. A new set of optical potential parameters is found. Analyses of the [math] nuclear reactions are carried out for the levels of excitation 3.089, 8.86 and 9.87[math]MeV. The single particle [math], and cluster [math] models are applied in calculations of differential cross-sections. The calculations show that the state 3.089[math]MeV is populated with the single particle configuration, while the latter bands 8.86[math]MeV and 9.87[math]MeV mainly have the cluster [math] excitation. The major contribution of the Hoyle state of the core [math] is not observed, but the cluster [math] configuration is ascertained to be the main contributor to the state 8.86[math]MeV.

  • Event-shaped-dependent cumulants in p-Pb collisions at 5.02[math]TeV

    • Free pre-print version: Loading...

      Authors: De-Xian Wei, Li-Juan Zhou
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      In this paper, we present a novel event-shaped cumulants (ESC) response approach, based on a multi-phase transport (AMPT) model simulations, to analyze p-Pb collisions at [math] TeV. We find that the Pearson coefficients between the subset cumulants of the final harmonics [math] and the subset cumulants of initial eccentricity [math] in the ESC basis are significantly enhanced. These Pearson coefficients are strongly-dependent on the charged multiplicity, the set number of events (SNE), and only weakly-dependent on the order of the multi-particle cumulants (two-particles, four-particles, and so on). Our results show that the ESC method can suppress the event-by-event fluctuations.

  • Energy transitions and half-life determinations of [math]Sc isotopes from
           photonuclear reaction on Ti target

      Authors: Gökhan Koçak, Serkan Akkoyun, İsmail Boztosun, Haris Dapo
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      For the activation of the target nucleus, bremsstrahlung photons generated in a medical linear accelerator can be used. Due to particle separation energy limitations for low photon energies in the giant resonance region ([math]18[math]MeV), the reaction exit channels are restricted to the ejection of one or two particles only. Thus, the gamma spectrum is relatively clear, and the use of ancillary detectors coupled to HPGe is not highly needed. In this study, the bremsstrahlung photons have been used for the activation of the titanium target. [math]Sc isotopes are observed from the natural titanium target via photo-proton reactions. Decay radiations from the isotopes and half-life of [math]Sc which is from the most abundant natural titanium have been determined consistent with the literature values.

      Abstract: International Journal of Modern Physics E, Ahead of Print.
      The [math] band in [math]Pd is investigated by the cranking covariant density functional theory (CDFT) with the particle-number-conservation shell-model-like approach (SLAP) to treat the pairing correlations. The experimental [math], moments of inertia, and the total angular momentum are well reproduced by our calculation. The deformations for neutrons, protons, and the whole nucleus behave in a similar way with the decreasing of [math] and the tiny change of [math] with increasing rotational frequency [math] from 0.2 to 0.6[math]MeV. The features of the antimagnetic rotation (AMR) are identified by above calculation results. To conclude, the configuration of AMR for [math]Pd given by the cranking CDFT-SLAP is [math]([math])[math]. Furthermore, the configuration of [math]([math])[math], which presents the experimental result of low spins, is also presented.

  • Apply the VDPC algorithm to the constraint Hatree–Fock theory: In

      Authors: J. Y. Hu
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      L. Y. Jia recently proposed an algorithm that applies the variational method directly to coherent-pair condensates (VDPC) [L. Jia, Phys. Rev. C (2019).] Now I’ll make changes to the VDPC algorithm that applies it to the Constraint Hatree–Fock theory. I derived expressions of the mean energy extremum with linear constraints and the analytic form of the Lagrangian multiplier. In addition, I acquire an angle through the inverse tangent of the energy minimum to the electric quadrupole moment in Fig. 3, which describes the unconstrained energy under an equivalent rotating system. I demonstrate the new algorithm in a semirealistic example using the realistic [math] interaction in the large model spaces (up to 15 harmonic-oscillator major shells). In this work, I am interested in a wave function [math], which minimizes the total energy under the constraint that has a fixed expectation [math]. I graphed the results as just an energy extreme versus electric quadrupole moment graph. The result shows that Fig. 3 is similar to Fig. 7.2 in [P. Ring and P. Schuck, The Nuclear Many-body Problem (Springer Science & Business Media, 2004)].

  • Macroscopic versus microscopic models in predicting [math]-decay
           half-lives of actinide nuclei

      Authors: G. R. Sridhara, H. C. Manjunatha, R. Munirathnam, N. Sowmya, H. B. Ramalingam
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      This paper investigates the predictive power of the macroscopic and microscopic models in alpha-decay of actinide nuclei. Macroscopic theoretical models such as Coulomb and Proximity potential model (CPPM), Modified generalized liquid drop model (MGLDM) and Effective liquid drop model (ELDM) are applied in predicting the alpha-decay half-lives of actinide nuclei. The half-lives produced by these macroscopic models are compared with that of microscopic models such as Cluster model with two-potential approach (CM), Microscopic cluster model (MCM), Multichannel cluster model (MCCM) and that of experiments. The deviation of these models with the experiments is quantified using statistical treatment such as root mean square deviation [math] (RMSD), mean deviation ([math]), index [math] and root mean square error (RMSE). It is found that among the microscopic and macroscopic models, ELDM and MCCM are, respectively, found to be accurate than that of other models. The microscopic model MCCM produces alpha-decay half-lives close to the experiments in the actinide region. The appropriate mass excess values have been identified to predict the exact alpha-decay half-lives in the actinide region.

      Abstract: International Journal of Modern Physics E, Ahead of Print.
      Employing Coulomb and proximity potentials, cluster-decay half-lives ([math]) of even–even nuclei had been calculated and, the obtained results are compared with the experimental ones. To investigate cluster radioactivity in superheavy nuclei (SHN), we determine the required disintegration energies ([math]-values) utilizing periodic-orbit theory within microscopic-macroscopic formalism and hence, predict the logarithmic values of [math] for even–even SHN with [math], 124 and 126. Among various isotopes of daughter nuclei, products produced with minimum value of Gibbs free energy are chosen for our investigation. Moreover, study of the branching ratios would make us to find the dominant mode of decay among [math]-decay, spontaneous fission (SF) and cluster-decay in these SHN. Mostly, the emissions of Kr-, Sr-, Zr- and Mo-clusters from these superheavy nuclei are found to be the dominant modes of decay which can be attributed to strong shell effects in the neighborhood of [math] region. Our results are in agreement with those obtained using UDL method except for few cases. We believe that this work can play a significant role in the study of decay properties of superheavy nuclei.

      Abstract: International Journal of Modern Physics E, Ahead of Print.
      The available experimental data for the elastic scattering of isobar nuclei 6Li and 6He on [math]C nuclei have been reanalyzed in a wide energy range of energy from 5.8[math]MeV to 600[math]MeV using the optical model with Distorted Wave Born Approximation (DWBA), and coupled reaction channel method (CRC) where inelastic scattering and transfer have been involved during calculations. A semi-microscopic potential, namely double-folding cluster model (DFC) has been used to investigate the cluster structure for both projectiles and target which was folded with Distorted Wave Born Approximation (DWBA) as a real part of potential where the imaginary part was taken in Woods–Saxon (WS) shape. The crystal model method has been applied to 6Li, 6He elastically scattered by [math]C, and reliable analysis of the considered experimental data has been obtained.

      Abstract: International Journal of Modern Physics E, Ahead of Print.
      The study of neutron-deficient Kr isotopes in mass range [math]–80, which is in the transitional region, is quite interesting. These isotopes show different structures, particularly in [math] shape coexistence near ground state has been observed. In this work, the multi-quasiparticle triaxial projected shell model (TPSM) is employed to study the high spin band structures and to depict [math] deformation in [math] nucleus. A triaxial configuration is a superposition of several K-states and the projected states result in various bands originating from the same intrinsic configuration. The yrast-, [math]- and 2[math] bands are studied and explained in the framework of TPSM approach.

      Authors: Sh. Hamada, Awad A. Ibraheem
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      We have investigated the threshold anomaly observed in 7Li + [math]Pb nuclear system by analyzing the available 7Li+[math]Pb experimental angular distribution measurements. The experimental data for the weakly bound 7Li ions elastically scattered from [math]Pb target at 13 energy sets ranging from 25.67 and up to 68[math]MeV are subjected to detailed analysis using different interaction potentials created either based on phenomenological, semimicroscopic and microscopic models. The loosely bound nucleus 7Li, possessing a predominant [math] cluster structure at 2.468[math]MeV, is a good candidate as its break-up reaction studies would help to understand the break-up of the weakly bound unstable radioactive isotopes. In order to observe the break-up effect, reaction cross-sections are extracted and compared with the previously reported ones.

  • Influence of nucleon structure on spin correlation coefficients in elastic
           lepton-deuteron scattering

      Authors: Eed M. Darwish, A. Mindil
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      Spin correlation coefficients in elastic scattering of leptons on the deuteron are studied in the one-photon-exchange Born approximation within the limit of zero lepton mass. Numerical estimations for the spin correlation coefficients caused by a polarized beam and a vector polarized target are presented and analyzed at various beam energies and scattering angles in two coordinate systems which are relevant for experiment. The influence of the obtained results on the nucleon structure is investigated, and a considerable dependence at incident beam energies greater than 1[math]fm[math] and backward scattering angles is found. The estimated results are of particular interest for encouragement of experimental measurements of lepton-deuteron scattering which aim for accurate calculation of the charge radius of the proton to a high degree of precision. These results may also stimulate new generation of measurements of different physical observables very sensitive to the spin structure of the nucleon and light nuclei.

      Abstract: International Journal of Modern Physics E, Ahead of Print.
      Neutrinos play an important role in core-collapse supernova events since they are a key piece to understanding the explosion mechanisms. The analysis of the neutrino fluxes can bring answers to neutrino’s related problems e.g., mass hierarchy, spectral splitting, sterile neutrinos, etc. In this work, we study the impact of neutrino oscillations and the possible existence of eV sterile neutrinos upon the supernova neutrino flux ([math]). We have calculated the energy distribution of the neutrino flux from a supernova and the total number of events that would be detected in a liquid scintillator. We also present an analysis for the conversion probabilities as a function of the active-sterile neutrino mixing parameters. Finally, we have carried out a statistical analysis to extract values for the mixing parameters of the model.

      Authors: B. Mukeru, L. V. Ndala, M. L. Lekala
      Abstract: International Journal of Modern Physics E, Ahead of Print.
      Breakup reactions involving heavy targets are known to be dominated by the Coulomb breakup, and this is understood as due to the long-range nature of Coulomb forces and a large charge of the target nucleus. In this paper, we intended to find out whether these two factors alone can justify the large importance of the Coulomb breakup over its nuclear counterpart. To this end, we considered the [math] breakup reaction at an incident energy of [math]. By analyzing this reaction, it is found that the continuum–continuum couplings and higher-order multipole transitions, which are characteristic of nuclear reactions induced by loosely bound projectiles, strongly suppress the nuclear breakup cross-section and have a negligible effect on the Coulomb breakup cross-section. When these reaction dynamics are removed, the nuclear breakup cross-section becomes more important than the Coulomb breakup cross-section at large incident angles. In conclusion, these results infer that the predominance of the Coulomb breakup over the nuclear breakup in reactions involving heavy targets can be explained by three main factors: the large target charge and the long-range nature of Coulomb, as well as the prevailing reaction dynamics such as continuum–continuum couplings and higher-order multipole transitions. These results could motivate further improvements on the theoretical approaches used in pure Coulomb breakup calculations.

      Experimental results on the search and investigation of the possible pp[math] resonance states in inelastic [math]C[math]C collisions at 3.37 [math] GeV are presented. The statistically significant peak structure with mass [math][math]MeV and Breit–Wigner width [math][math]MeV has been observed for the first time in the spectrum of invariant masses of pp[math] system in [math]C[math]C collisions at 3.37 [math] GeV . The inclusive cross-section of the formation of this possible eight quark pp[math] resonance state has been estimated to be [math][math]mb. The significant maximum structure with the center estimated at [math][math]MeV, and having a narrow width ([math][math]MeV), has been observed in the spectrum of the invariant masses of two protons in [math]C[math]C collisions at 3.37 [math] GeV when the value of the invariant mass [math] of the pp[math] system falls inside the region of the observed pp[math] resonance structure: [math][math]MeV.

      Abstract: International Journal of Modern Physics E, Ahead of Print.
      The aim of the AMADEUS collaboration is to provide new experimental constraints to the antikaon-nucleon ([math]) strong interaction in the regime of nonperturbative QCD, investigating the low-energy [math] hadronic interactions with light nuclei like H, 4He, 9Be and [math]C. The unique low-momentum kaon beam produced at the DA[math]NE collider is ideal to study [math] nuclear captures, both at-rest and in-flight. The large acceptance KLOE detector, used as an active target, allows to achieve excellent position and momentum resolutions. In this work, a brief description of recent AMADEUS results is presented.
