判断原子态有无磁矩的方法

A Method of How to Judge the Moment of Magnetism in Atomic State

介绍一种直接判断朗德g因子是否为零的方法 ,从而可方便地判断原子态是否有磁矩 ,同时讨论了g =0时的原子矢量模型 。

A direct judging method is introduced about whether Langde g factor equals zero or not, so that it can be easily decided whether there is moment of magnetism in atomic state. Meanwhile, the atomic vector model is discussed when g=0, and finally, it is pointed out whether atomic energy step spilits in external magnetic field. [
