摘要:  强电场情况下，微扰论不再适用，要精确求解Ｓｃｈｒｏｄｉｎｇｅｒ方程．本课题组用数值方法对强电场下类氢原子电离进行了计算，得到基态氢原子的共振态解，与更精确的结果作了比较，证明Ｂｒｅｉｔ－Ｗｉｇｎｅｒ近似在一定误差下是可以接受的． The Schrdinger equation of hydrogen like atoms in a strong electric field is solved by the numerical method instead of perturbation. The resonance ionization of hydrogen atom ground state is computed and comparing with exact result and Breit Wigner parametrisation is useful.
