“…The semi-microscopic approach used in this study can successfully reproduce data of the recently discovered superheavy element 294 Og and other Og isotopes, whose accuracy corresponded well with the experimental data [45]. Further, it accurately predicts the masses and deformations for heavy and superheavy nuclei similar to the prevalent microscopic and semi-microscopic models [19,46,47].…”

“…The most notable alternative to the self-consistent method is the semi-microscopic method [40,41] with strutinsky shell-correction [42,43], where the energy of a nucleus is considered to be the sum of its macroscopic and microscopic components. In addition to its simplicity, the semi-microscopic technique is successful in studying the nuclear structure [19,20,[44][45][46][47] anddecay [48]. The semi-microscopic approach used in this study can successfully reproduce data of the recently discovered superheavy element 294 Og and other Og isotopes, whose accuracy corresponded well with the experimental data [45].…”

“…In this study, the total energy is evaluated in the framework of the semi-microscopic approach reported in [19,46]. In this method, the macroscopic component of the total energy is considered by the energy density functional, with the Skyrme force, SkM*, as a function of the nucleon densities, , and kinetic energy densities, , Chinese Physics C Vol.…”

In this study, two novel improvements for the theoretical calculation of neutron distributions are presented. First, the available experimental proton distributions are used as a constraint rather than inferred from the calculation. Second, the recently proposed distribution formula, d3pF, is used for the neutron density, which is more detailed than the usual shapes, for the first time in a nuclear structure calculation. A semi-microscopic approach for binding energy calculation is considered in this study. However, the proposed improvements can be introduced to any other approach. The ground state binding energy and neutron density distribution of 208Pb nucleus are calculated by optimizing the binding energy considering three different distribution formulae. The implementation of the proposed improvements leads to qualitative and quantitative improvements in the calculation of the binding energy and neutron density distribution. The calculated binding energy agrees with the experimental value, and the calculated neutron density exhibits fluctuations within the nuclear interior, which corresponds with the predictions of self-consistent approaches.

“…With the progress on the synthesis of SHN, many theoretical methods for the nuclear structure study were developed . They can be divided into the following three categories: the Macroscopic-Microscopic (MM) models [12][13][14][15][16], non-relativistic mean field approaches [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] and relativistic mean field approaches [30][31][32][33][34][35][36][37][38][39]. Since the existence and stability of SHN are closely associated with shell effects, it is very important to search for the magic numbers in the superheavy mass region, which may be the most important issue for the study of SHN.…”

The two-neutron separation energies (S2n) and α-decay energies (Qα) of the Z = 114 isotopes are calculated by the deformed Skyrme–Hartree–Fock–Bogoliubov (SHFB) approach with the SLy5, T22, T32 and T43 interactions. It is found that the tensor force effect on the bulk properties is weak and the shell closure at N = 184 is seen evidently with these interactions by analyzing the S2n and Qα evolutions with neutron number N . Meanwhile, the single-particle energy spectra of 298114 are studied using the spherical SHFB approach with these interactions to furthermore examine the shell structure of the magic nucleus 298114. It is shown that the shell structure is almost not changed by the inclusion of the tensor force in the Skyrme interactions. Finally, by examining the energy splitting of the three pairs of pseudospin partners for the protons and neutrons of 298114, it is concluded that the pseudospin symmetry of the neutron states is preserved better than that of the proton states and not all of the pseudospin symmetries of the proton and neutron states are influenced by the tensor force.

“…For example, non-relativistic self-consistent Hartree-Fock approach using Skyrme like interactions [21] or in the framework of the relativistic mean field theory [18,22] predict probable shell closures at Z = 114, 120 and 126. In addition, the minimization procedure of the total energy, including shell and pairing energies, of a nuclear system with respect to proton and neutron numbers predicts magic numbers and give idea about the relative stability of different nuclei [23][24][25]. Recently, the behavior of half-life time of α-decay with variation of proton or neutron numbers and the study of α-particle preformation probability were used to predict new magic numbers or to confirm known magic numbers found by other different methods [1,26].…”
