摘要
以入射能量为６４．６ｅＶ、能量均分、共面不对称几何条件下Ｈｅ原子电子碰撞电离过程为例，分析低能（ｅ，２ｅ）反应中的碰撞机制、交换效应和卢瑟福散射效应，揭示了两种新的碰撞机制（ＤＢ碰撞和ＴＢ碰撞）的物理实质。
This work analyses the collision mechanisms, exchange effects and Rutherford
scattering in the low energy (e,2e) reactions through the study on electron impact ionization
of helium in the coplanar asymmetric geometry with equal energy sharing. It has been shown
that the Rutherford scattering plays a significant role in the two new collision processes named
as DB and TB collision.
