采用扭曲波方法对电子与钠原子非弹性散射截面，及与散射过程有关的极化参数进行了计算，将所得结果与实验值和CCC方法所得结果进行了比较.可以看出在中高能(5—10倍阈能)领域，扭曲波法是一种模型清晰、结果可靠的方法.The differential cross-section and parameters of polarization in electron-atom(Na) collision are calculated by the Distorted Wave Method(DWM) in this work.The results are compared with those of experiment and those obtained by Convergent Closed Coupling(CCC) method.It is shown that the DWM is a reliable method with a clear model in moderate to high energy region (5—10 times of threshold energy).
