| 摘 要： | 利用(e,2e)反应中跃迁矩阵的后滞形式,忽略了质心运动和相对运动的情况下,计算基态氢原子单离化的三重微分散射截面,与相关的实验结果符合的较好.笔者的近似计算能较好的反映基态的散射过程,计算量较小,该方法可以进一步推广到激发态散射截面的计算中.

| Abstract: | Taking use of the post form of transition matrix of the (e,2e) reaction and omitting the motion of center of mass and contrary motion,the authors calculate the triple differential cross section(TDCS) of the hydrogen atom singly ionized by the impact of electron under ground state.The theoretical calculations have good agreement with the experimental results.Out results demonstrate the scattering process reasonably and the theoretical calculation is not so complex.This approximate method would be appropriate... |
