论文摘要
已经分析了SI，S，AR和CA中均匀同位素的壳结构。壳闭合参数$ d_ {n}（n）$的理论计算以及两中性分离能量$ ds_ {2n}（z，n）$的差异变化是在Hartree-Fock-Bogoliubov理论的框架内进行的。对不同的天际力进行了计算，并且已经测试了它们的灵敏度。通过基于介子交换和点耦合模型采用相对论的平均场凹陷来研究相同的核素。理论上计算的估计值与最近可用的实验数据非常吻合，该数据在AR和CA同位素中的Si和n = 20和28中的Si，n = 14、20和28的情况下，在n = 14和20的壳闭合签名。
The shell structure of even-even isotopes in Si, S, Ar and Ca has been analysed. The theoretical calculations of shell closure parameter $D_{n} (N)$ and the differential variation of the two-neutron separation energy $dS_{2n} (Z, N )$ are carried out within the framework of Hartree-Fock-Bogoliubov theory. Calculations are carried out for different skyrme forces and their sensitivity has been tested. Same nuclides are studied by employing the relativistic mean field aproach based on meson exchange and point coupling models. Theoretically calculated estimates are in good agreement with the recently available experimental data which fortifies signature of shell closure at N = 14 and 20 in case of Si, N = 14, 20 and 28 in S and N=20 and 28 in Ar and Ca isotopes.
