摘要

摘要证明了在核电荷数为 Z = 124 的原子激发态和 Z = 125 的原子基态（属于扩展周期表的第 8 周期）中存在 g 轨道的轨道塌缩。在这两种情况下，当增加总角动量 J 时，轨道塌缩会在同一构型内发生，而总角动量 J 是原子在 jj 耦合中的相对论项的特征。所有计算都是通过相对论 Dirac-Fock 方法进行的。

Orbital Collapse of the 5g-Electrons in the Superheavy Elements of the 8th Period

The presence of the orbital collapse of the g-orbitals in the excited state of the atom with the nuclear charge number Z = 124 and in the ground state of the atom with Z = 125, which belong to the 8th period of the extended periodic table, is demonstrated. In both cases, the orbital collapse occurs within the same configuration when increasing the total angular momentum J, which characterizes the relativistic term of the atom in the jj coupling. All calculations are performed by means of the relativistic Dirac–Fock method.
