对等效势模型中的极化势进行了修正，使其在近区描述的入射电子对靶原子的极化作用更符合实际。计算了电子与氧原子碰撞的弹性总截面、动量转移截面和微分截面，结果有较大改进，与其他的实验和理论值符合得很好。

The equivalent potential model is usually used for electron - atom collision . The polarization effects caused by the incident electrons have been studied in this paper ,and the polarization potential has been modified to describe the polarization effects nearby the target atoms sufficiently .The total ,momen‐tum transfer and differential cross sections have been calculated for the electrons elastic collision with oxy ‐gen atoms .The results show great improvement and agreed well with other experimental and theoretical results .
