摘要
用包含极化效应和后碰撞作用的扭曲波玻恩近似计算共面不对称几何条件下A r 3s的低能(e,2e)三重微分截面,并与实验进行比较。指出极化效应在共面不对称几何条件下A r 3s的低能(e,2e)过程中起着重要的作用。
The distorted wave Born approximation with polarization and post-collisional interaction has been used to calculate the triple differential cross sections for low-energy electron impact ionization of the 3s orbital of argon in coplanar asymmetric geometry.The calculated results are compared with available experimental data.It is noted that the polarization effect plays an important role in the low-energy(e,2e) processes of Ar 3s in coplanar asymmetric geometry.
