电子与第二周期原子碰撞的规律研究

Study of Collision Rule of Electron and the Second Cycle Atom

首先采用处理慢电子被原子散射的等效势模型,用分波法计算了能量在0.1 eV^15 eV范围内电子与氮原子系统的弹性散射总截面;其次讨论了Hammerling交换势中比例系数γ取不同数值时对结果的影响;最后总结了低能电子与第二周期元素原子碰撞时交换势中比例系数γ的取值规律。

The total elastic scattering cross-section of electron and nitrogen atom was calculated by using the equivalent potential model and partial wave, which were often used to cope with the scattering process of electron and atom. The range of electron energy was 0. 1 eV - 15 eV. Then how the result varied with the Hammerling＇s exchange potential coefficient T was discussed. In addition, the dereferencing rule of coefficient 3＇ in the collision of low-energy electron and the elements of the second cycle was summarized.
