摘要
本文在研究极化效应的长程极化和近区关联特性基础上,对常用的极化势公式进行了修正,使其在近区具有良好的物理性能。以低能电子与隋性气体重原子氪弹性碰撞为例,考虑相对论效应,在0.4—30eV能量范围内计算了弹性散射微分截面和总截面,获得了满意的截面数据。结果表明,本文提出的修正是成功的。
A modification for the widely used polarization potential was made in the present paper. The modified polarization potential was employed to investigate e-Kr low-energy elastic scattering processes,in which the exchange and relativistic effects were included also by using the semi-classical exchange approximation and semi-relativistic potential respectively. Partial-wave phaseshifts and differential and total cross sections were calculated and compared with recent experimental and other theoretical work in energy region 0.4-30eV.
