中文摘要：

在电子入射方向平行于激光场的极化方向这种特殊的散射模式下，把二阶玻恩近似理论推广到电子与较重惰性原子-氙原子散射的过程，计算了小角度（5°～25°）情况下激光辅助电子与氙原子散射交换单光子、双光子和三光子的微分散射截面．并对计算结果进行了分析，对比电子与其它惰性原子散射过程，表明用二阶玻恩近似理论解释在激光场下电子与较重惰性原子散射也是比较成功的．

英文摘要：

In this paper, the second Born approximation （SBA） is extended to the electron and the heavy inert atom scattering in the special scattering geometry that the incident electron beam is parallel to the polarization direction of laser field, and the research performs exact numerical calculation of differential cross sections （DCS） of laser-assisted electron-Xe scattering with one-, two-, and three-photon exchange at small scattering angles （5° - 25°）. Compared these results with other inert atom scattering, the results show that the second Born approximation succeed in explaining electron and heavy inert atom scattering in laser field.
