摘　　要：文中基于光学模型势方法，详细分析并改进了一种准自由模型吸收势，把它作为光学模型的虚部，在能量０．１－３００ｅＶ的范围内计算了电子被Ａｒ，Ｋｒ，Ｘｅ原子散射的总截面，计算结果与实验值进行了比较。A new quasifree-scattering model potential is presented and carefully researched based on the method of optical model. Regarding it as the imaginary po of the optical model, we calculated the total cross sections of electron scattering from Ar, Kr and Xe atoms, and the results is nicely in agreement with that of the experiments from 0. 1eV to 300eV.
