摘要/Abstract

摘要： 采用全相对论多组态Dirac-Fock方法,分别计算了类锂离子(Z=3~100)的磁偶跃迁1s²3s²S_1/2→1s²2s²S_1/2和电偶跃迁1s2p²P_1/2→1s²2s²S_1/2的能级间隔,QED贡献和跃迁几率,比较了两者的参数与核电荷数Z的关系的差异.认为原子序数很大时,磁偶跃迁几率不能忽视.

关键词: 磁偶极, 电偶极, 类锂离子, 跃迁几率

Abstract: Energy level intervals, QED contributions and transition probabilities of magnetic dipole (M1) and electronic dipole (E1) for 1s²3s²S_1/2→1s²2s²S_1/2,and 1s²2p²P_1/2→1s²2s²S_1/2 transitions are calculated for the Li-like ions (Z=3~100) using the fully relativistic multiconfiguration Dirac-Fock method with Breit and QED correction. Comparisons between the M1 and E1 transitions are made.

Key words: magnetic dipole, electronic dipole, Li-like ion, transition probability
