本文系统地研究了镁原子电子碰撞电离的三重微分截面。对于一系列不对称的运动学状态，给出了使用第一波玻恩近似和扭曲波波恩近似的完整的理论结果。不同近似的物理意义如何进入横截面的特征将被清楚地演示。与马里兰小组的实验进行了比较，并对新的实验提出了建议。
A systematic study of the triple differential cross section for the electron impact ionization of magnesium is presented. Complete sets of theoretical results using both the first Born and the distorted wave Born approximation are given for a range of asymmetric kinematical regimes. How the physical significance of the different approximations enter the character of the cross sections will be explicitly demonstrated. Comparison is made with experiments of the Maryland group and suggestions are made for new experiments.
