用相对论Hartree-Fock方法和多组态Dirac-Fock方法计算了镉等电子序列中允许和禁止自旋的5s{sup 2}{sup 1}-5s5p{sup 1，3}p{sub1}{sup o}57跃迁的振子强度，其中包括核-极化势和多组态Dirac-Fock方法，并考虑了价和核-价关联效应。当比较两组理论数据以及比较自旋禁忌跃迁的理论和实验时，注意到很好的一致性。单线态-单线态转变的理论(两种理论都是一致的)与实验之间的差异表明，一些实验数据需要修正。(C)2000年美国物理学会。
The oscillator strengths of the allowed and spin-forbidden 5s{sup 2} {sup 1}S{sub 0}-5s5p {sup 1,3}P{sub 1}{sup o} transitions in the cadmium isoelectronic sequence are evaluated for 48{<=}Z{<=}57 using the relativistic Hartree-Fock approach, including a core-polarization potential, and the multiconfiguration Dirac-Fock method, taking the valence and core-valence correlation effects into account. A good agreement is noted when comparing the two sets of theoretical data and when comparing theory with experiment for the spin-forbidden transition. The discrepancies observed between theory (both theories being in agreement) and experiment for the singlet-singlet transition indicate that some experimental data are in need of revision.
