摘要

利用基于多组态Dirac-Fock理论方法的原子结构及性质计算程序GRASP92, 详细研究了类氟W65+到类锂W71+离子的2p3/2—2s1/2跃迁性质. 计算结果与Podpaly等[Phys. Rev. A 80 052504 (2009)]的实验结果符合得非常好. 在此基础上, 利用全相对论扭曲波方法研究了2s1/2—2p3/2的电子碰撞激发总截面和磁子能级碰撞激发截面以及部分谱线的线性极化度, 分析了电子碰撞激发截面和谱线线性极化度随碰撞能量的变化规律.

Abstract

In this paper, the excitation energy and radiative transition probabilities are calculated for 2p3/2-2s1/2 transition in W65+ through W71+ ions, by using GRASP92 package based on the multi-configuration Dirac-Fock method. The present calculations are compared with other theoretical and experimental results [Podpaly et al. 2009 Phys. Rev. A 80 052504], and they are in good agreement each other. Furthermore, the total cross section and the magnetic sublevels cross section for the 2s1/2-2p3/2 excitation in W65+ through W71+ ions as well as the polarization of resulting transitional lines are calculated, with a fully relativistic distorted-wave method. Based on the calculation, the variations of the excitation cross sections and polarization with the increase of incident electron energy are discussed systematically.
