摘要
朗德g因子是表征原子的磁矩与角动量之间关系的一个无量纲的物理量。它决定了能级在磁场中分裂的大小,并且对于正常塞曼效应和反常塞曼效应的产生也可以给出定量的解释;在不同类型的原子中,朗德g因子的值也会不同,这对物质结构的分析也有很大帮助。另外,朗德因子在分析原子的顺磁共振以及核磁共振等现象中也起着不可忽视的作用。该文详细讨论了在各种情况下原子磁矩与角动量的关系,计算得到了jj耦合情形下的朗德因子。
Lande g factor is a nondimensional physical quantity which represents a relationship between the atomic magnetic moment and angular momentum.It decides the size of the energy level splitting in the magnetic field,and can also give a quantitative explanation for the formation of normal zeeman effect and anomalous zeeman effect.The value of Lande factor will be various in different types of atoms,so it is beneficial for us to analyze material structure.In addition,Langde factor plays a nonnegligible role in analysis of the paramagnetic resonance of atomic and nuclear magnetic resonance.Therefore,this article will discuss in detail about different cases of Langde factor by calculation.
