论同科电子P^2组态的光谱项及光谱支项

Discussion about the spectroscopic terms and spectroscopic branched terms of the P ~2 configuration of the eguivalent electrons

根据电子排布法按保里原理的要求 ,将给定的组态的电子分别排布在各可能的轨道上 ,然后在可能的电子排布的微观状态中找出MS 的最大值 (MS) max,以及与之相适应的 (ML) max,根据这两个值找出S和L值 ,得出光谱项 ,再将ML 和MS 偶合 。

According to the method of electronic configuration and Pauli principle,the electrons of definitive configura-tioon are configurated separately in each possible orbit,then the maximum of M s is found among the possible microcosmic states of electronic configuration,according to (M s) max and (M L) max ,the value of S and L is found,the spectroscopic terms is ob-tained,by coupling of M L and M S,the spectroscopic branched terms is obtained too.
