The charge, proton and neutron density distributions along with nuclear properties were calculated by Hartree–Fock approach with Skyrme force interaction for isotopic Pb chain ([Formula: see text]). The effects of correlation on neutron skin thicknesses by obtaining bulk and surface contributions were analyzed by three different approaches. The occurrence of the nuclei with bubble structure due to central depletion in nucleonic was investigated for Pb isotopes as a function of relative neutron excess [Formula: see text]. The important role of the bubble effect in heavy region was explained by the relation between Coulomb and nn-interaction. The single particle energy levels were determined by each [Formula: see text] state of stable Pb isotopes, as well as charge form factors [Formula: see text]. Besides, the average neutron–proton [Formula: see text] and residual neutron–proton [Formula: see text] interactions of the Pb isotopes were calculated by the theoretical binding energies. The fluctuations in the obtained results were considered in detail because its variation may give a good criterion for the mass model approaches.

中子星的核结构特性

电荷、质子和中子密度分布以及核特性通过 Hartree-Fock 方法和同位素 Pb 链的 Skyrme 力相互作用计算（[公式：见正文]）。通过三种不同的方法分析了通过获得体积和表面贡献来分析相关性对中子表皮厚度的影响。研究了 Pb 同位素与相对中子过量的函数关系，研究了由于核子中的中心耗尽导致的具有气泡结构的核的出现 [公式：见正文]。重区气泡效应的重要作用可以通过库仑和 nn 相互作用之间的关系来解释。单个粒子的能级由稳定 Pb 同位素的每个 [公式：参见文本] 状态以及电荷形式因子 [公式：参见文本] 确定。此外，平均中子-质子 [公式：见正文]和残余中子-质子[公式：见正文] Pb 同位素的相互作用是通过理论结合能计算的。详细考虑了所得结果的波动，因为它的变化可以为质量模型方法提供一个很好的标准。
