摘要
用BBK(Brauner,Briggs,Klar)模型和修正后的BBK模型在大的能量损失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和研究,并把计算结果与Catoire等的实验测量结果以及Stevenson等的最新实验测量结果进行了比较,对作者早期文章的理论推论进行了验证,并对交换效应作了系统的研究.
The triple differential cross sections for electron impact ionization of helium in the special geometry of coplanar large energy loss are calculated by using the BBK model and the modified BBK model.The calculated results are compared with the experimental results of Catoire and the present experimental results of Stevenson.The previous theoretical deduction is proved and the exchange effects are analyzed and discussed.
