摘要
基于量子微扰理论,研究了渐变磁场下塞曼效应的变化规律。结果表明,在强磁场作用下,发光原子表现为正常塞曼效应;在弱磁场下表现为反常塞曼效应;当磁场由弱逐渐增强到足以忽略耦合能的极限条件下,所有发光原子都表现为正常塞曼效应。
Based on quantum perturbation theory,it studied the rule of Zeeman effect＇s change in gradual magnetic field. The result showed that the glowing atom appears normal Zeeman effect in the powerful magnetic field and appeared abnormal Zeeman effect in the weak magnetic field. When the magnetic field gradually increased to critical condition in which the coupling energy was ignored,all glowing atoms appeared normal Zeeman effect.
