共面非对称条件下Ar原子2p壳层三重微分截面的计算

Calculation of Triple Differential Cross Section for Argon 2p Orbital in Coplanar Asymmetric Geometry

将极化效应引入畸变波玻恩近似(DWBA)方法中,得到修正的DWBA理论.计算共面非对称动力学条件下,Ar原子2p壳层的三重微分截面,结果表明,极化效应在Ar(2p)电离过程中作用较大.

We modified the distorted wave Born approximation method （DWBA） by introducing polarization interaction into the distorted potential of DWBA. The triple differential cross section （TDCS） of the argon 2p orbital in a coplanar asymmetric geometry was calculated, Calculational results by means of the modified DWBA method show that polarization effects are very important for ionization of argon 2p shell.
