量子场论方法在电子与分子碰撞中的应用

摘要

这是一种利用量子场论所进行的探究性的研究方法,在文章中,我们设 计了一种新的较为简单的电子-原子碰撞模型,将量子场论方法与光学势方法中的可加性规 则结合起来.利用这种模型,我们计算了e-H,e-He和e-Li的微分碰撞截面,获得了较满意的 结果.%This is a tentative research method for electron-atom col lision using quantum field theory. In this paper, we designed a new simple model of electron-atom collide process. The quantum field theory is combined with ad ditivity rule in this model. Through this model we calculate the differential cr oss section for e-H, e-He and e-Li collision. the result is quite encouraging ; the physical ideology is new and innovational for further study.
