采用修正的扭曲波玻恩近似(DWBA),在共面非对称几何条件下,计算了Ar(3p)原子被70.8eV电子碰撞电离的(e,2e)三重微分截面,并与Ren等人的实验数据进行了比较.结果表明,电子交换效应和碰撞后相互作用(PCI)在低能电子碰撞的(e,2e)过程中起重要作用。
(e, 2e) triple differential cross sections for the ionization of Ar (3p) by 70.8 eV electron impact are calculated in the coplanar asymmetric geometry using the modified distorted-wave Born approximation (DWBA), and compared with the recent experimental data of Ren et al.. The results show that electron exchange effect and post-collision interaction (PCI) play an important role in the (e,2e) process of low-energy electron impact.
