Sm^(2+)离子的激发态能级

Energy Levels of Sm^(2+) Excited State

本文采用U群方法计算了Sm^(2+)离子的激发态4f^5n′l′的主要谱项能级,给出了以Slater积分为参数的表达式。并顾及自旋-轨道耦合,按Russell-Saunders近似计算了相应能级的耦合参数λ。

The present paper covers energy levels of excited configurations 4f^5n^tl^t of Sm^(2+) calculated in detail by using unitary group approach. The energy expressions with slater integral as parameters are given and the spin-orbit coupling is considered according to the Russell-Saunders approximation. The coupling parameters λ of the main energy levels are also calculated in the paper.
