摘　　要：提出了一个新的处理强光中基态氦原子阈上电离谱的解析模型。由这个模型算得的基态氦原子阈上电离谱同最近的实验结果作了比较。同时简单地讨论了现在的模型对先前的模型的改进。A new analytical model for the ATI spectra of ground state He-atom in strong laser fields is proposed in this paper.It is found that the calculated ATI spectra by the model fits the recent experimental spectra very well.At same time,some improvements on the previous models made by the present model are briefly discussed.
