摘要
本文利用二阶玻恩近似方法 ( SBA)对激光辅助 e-Ar的碰撞进行了研究 ,在两种特殊的散射几何G1 和 G2 下 ,计算了交换多个光子的微分散射截面 .和实验相比 ,我们的结果明显好于其它理论结果 .
Electron scattering from argon in laser field is investigated employing the second order Born approximation. The absolute differential cross sections of e Ar scattering with multi photon exchange in the special geometries G 1 and G 2 are calculated. Our results are better than other theoretical results compared with the experiment at small scattering angles.
