【摘要】 构造了一种简化的电子与原子碰撞的复合势原子模型,并结合势能独立性原理的思想,研究了中等能量电子对原子的散射,得出了电子受原子散射的各种截面的理论计算公式,探索性地将独立性原理方法应用于电子与原子的碰撞截面的计算.应用复合势模型编程计算了电子被氦原子散射的总散射截面,计算结果与实验数据较符合.更多还原

【Abstract】 A tentative research method for electron-atom collision is established out,and a new simple model of electron-atom collision procession is designed.With the method,the authors study on scattering cross sections for mediate-energy electron scattering on atoms.Then the expressions of scattering cross sections for electron-atom collision are obtained,and the total cross section for e-He collision calculated.Compared with the experimental data,the results are encouraging.It shows that the physical ideology is new and innovational.更多还原
