自旋轨道耦合因子对多重态能级次序的影响

Influence of Spinorbit Coupling Items on the Sequence of the Multimode Energy Levels

利用微扰方法计算出两个价电子自旋轨道相互作用的能级精细结构 ,对给定电子组态 ,经过LS耦合所形成的多重态能级的讨论 ,得出能级次序由耦合因子A(LS)决定 ,并对He原子

This paper firstly figures out the subtle structure of the energy levels in which two electrons spinorbit interact by the method of minute disturbing, and then discusses the multinmade energy levels formed by certain electron's passing by the LS coupling items , finally draws the conclusion that the sequence of energy levels is determined by the coupling item A(LS),and gives explanation in the energy levels sequence of He atom's 1S2P mode as well.
