一种确定电子轨道自旋角动量耦合基矢的简便方法

A simple method to determine the coupling vectors of orbit-spin angular momentums

量子力学教材中对于多个角动量耦合基矢的确定,由于其计算上复杂,往往通过查表得到.以电子轨道自旋角动量耦合为例,介绍确定耦合基矢的另一种方法.结果表明,该方法简便,且对理论上计算原子光谱精细结构有十分重要的意义.

In most quantum mechanics textbooks, the determination of coupling vectors of multiple angular momentums was usually by looking up tables because of its complex calculation. It was introduced another method for the determination of coupling vectors, with the coupling of orbit-spin angular momentum of electrons as an example.
