摘　　要：文章利用简并态微扰理论,计算了弱外电场中氢原子n=4能级的一级和二级Stark效应.计算结果表明,外电场中,对于一级Stark效应,原来是16重简并的能级分裂成了7个能级;对于二级Stark效应,氢原子的16个态所形成16维子空间,且同一子空间的能级下移相同的量值,而不同子空间的能级下移量值不同.计算结果对弱电场作用下氢原子的光谱分析具有重要的意义.In this paper,the first and second order Stark effects of n=4 level of hydrogen atom in weak external electric field are calculated by using the perturbation theory of degenerate states.The calculation results show that in the external electric field,for the first order Stark effect,the original 16-fold degenerate splits into seven energy levels;for the second order Stark effect,the 16 states of the hydrogen atom form a 16-dimensional subspace,and the energy levels in the same subspace move down by the same amount,while the energy levels in different subspaces move down by different amounts.The calculation results have important significance and reference value for the spectral analysis of hydrogen atoms under the action of weak electric field.
