摘要

考虑了原子序数为112≤Z≤120的超重原子价电子密度的局域性，特别关注了原子序数为Z = 118的原子。如[P.]Jerabek et al.，物理学。应用电子局域化函数的非相对论性表达式，利用相对论性计算方法研究了原子壳层结构。物理学报，2012，(2018):551 - 551。通过在非相对论极限下进行相关计算，评价了相对论效应对价电子密度分布的影响。计算了单电子狄拉克-福克和哈特里-福克价层密度，没有发现这些密度被抹去的迹象。

Study of the valence electronic density distribution in Z=112-120 atoms

The localization properties of the valence electronic density are considered for superheavy atoms in the range of atomic numbers 112 ≤ Z ≤ 120, paying special attention to oganesson atom (Z = 118). As in [P. Jerabek et al., Phys. Rev. Lett. 120, (2018) 053001], the atomic shell structure is studied by means of the relativistic calculations using a non-relativistic expression for electron localization function. The influence of the relativistic effects on the distribution of the valence electronic density is evaluated by performing related calculations in the non-relativistic limit. One-electron Dirac-Fock and Hartree-Fock valence subshell densities are calculated and no signs of smearing out these densities are found.
