摘要
在前期工作的基础上 ,研究了共面等能几何条件下 ,电子入射离化氢原子三重微分截面的结构 .讨论了Brauner,Briggs和Klar理论的修正对截面结构的影响 .在两个出射电子相对角固定的情形下 ,验证了一种被称为“triple binary”碰撞的新的碰撞过程 .
Based on our earlier paper,the structure of the triple differential cross sections for electron impact ionization of atomic hydrogen in the coplanar equal energy\|sharing geometry is considered.It has been discussed how the influence of the modification of the Brauner,Briggs and Klar model on the structures of the cross sections.A new collision process called triple\|binary collision is verified in the situation where the angle of the two outgoing electrons is fixed.It has been shown how the position of all peaks and the dominant collision mechanisms change as the incident energy and relative angle increases.
