摘要: 用BBK模型和修正后的BBK模型在电子垂直入射几何条件下对氦原子的三重微分散射截面进行了理论计算,并把计算结果与实验测量结果进行比较,对截面的结构进行了分析,并对交换效应进行了系统的研究.Abstract: The triple differential cross section for electron impact ionization of helium in the perpendicular geometry is calculated by use of BBK model and modified BBK model.The results of the present work are compared with experimental data.The structure of the cross section is analysed and the exchange effects are discussed systematically.
