圆极化激光场中e-He散射

摘要

把二级玻恩近似(SBA)的方法推广至圆极化激光场，计算了发生多光子交换时的激光辅助电子被氦原子散射的微分散射截面。对计算结果进行了分析，并与线性极化激光辅助散射结果进行了比较。%In this paper, we extend the second Born approximation(SBA) to circular polarization laser, calculate the differential cross section(DCS) of laser-assisted e-He with multiphoton exchanging and analyze the results. We also compare these results with DCS of e-He in liner polarization laser.
