光学势在(e,2e)反应动力学过程的作用

Optical model potential effect in (e,2e) collisions of argon

将光学势包含到畸变波Bohn近似(DWBA)方法的畸变势中,修正了DWBA理论.计算了共面高非对称动力学条件下Ar原子2p壳层的三重微分截面,并与标准的DWBA计算得到的结果进行了比较.计算结果表明,光学势在Ar(2p)的电离过程中起着重要的作用.

We modify the distorted wave Bohn approximation method（DWBA） by introducing optical model potential into the distorted potential of DWBA in this paper.The triple differential cross section of the argon 2p orbital in a coplanar asymmetric geometry has been calculated,calculations using the modified DWBA method show that the optical model potential effects play an important role in the ionization of the argon 2p shell.
