电子与锂原子的弹性碰撞

Elastic collision of electrons and lithium atom

采用处理慢电子被原子散射的等效势模型,计算能量在0.1～15eV范围内电子与锂原子系统的弹性散射总截面和微分截面,并把计算结果与一些实验和理论值进行对比,结果吻合较好.另讨论了Hammerling交换势中比例系数γ取不同数值时对结果的影响.

The theoretical result of electron scattered by lithium atom in the rang of 0.1 ～ 20 eV was obtained with the equivalent potential model .Total elastic scattering cross section and differential cross section were calculated and compared with the previous more accurate experiment and other theoretical data.Our work were consistent well with others＇ work.The effects on the result induced by various γ in the Hammer ling＇s exchange potential were analyzed.
