摘要
用Mathematica和简并微扰理论计算了氢原子第一至第六激发态(2-7)在较强磁场中的能级分裂(不考虑自旋),并讨论了简并微扰理论的适用条件.数值结果表明:在微扰理论适用的条件下,磁场的一级修正可以使能级简并完全解除(2-7),但在一定条件下,可能会出现新的简并—偶然简并.微扰法对磁场强度有较苛刻的要求:对于较高激发态(例如4),当时微扰法失效;对于高激发态(例如7),当时微扰法就不适用了.
By using the Mathematica and perturbation theory,the energy level splitting (n =2-7) for the hydrogen atom in a stronger magnetic field is computed.The applicable condition of perturbation method is discussed.The numerical results show that:In general,the degeneracy of energy level (n =2-7) can be completely removed; But under certain conditions,there may be new degeneracy-accidental degeneracy.The perturbation method is strict about the strength of magnetic field:For the third excited states(n =4),when the perturbation method will not work; For the sixth excited states(n =7),when the perturbation method is not applicable.
