高电荷态N^(3+)共振光电离过程的相对论理论研究

Theoretical study of resonant photoionization process of highly charged ion N^(3+)

基于相对论多组态Dirac-Fock理论方法,利用细致平衡原理,系统研究了高电荷态N3+的共振光电离过程,计算了共振光电离过程的能量及截面,并与已有的理论和实验结果进行比较.结果表明,目前的理论计算很好地重现了实验谱,与已有的理论结果相比,本文的结果与实验具有更好的一致性.

Based on multiconfiguration Dirac-Fock method,the resonant photoionization process of highly charged ion N3＋ has been studied by using detailed balance principle.A systematic comparison has been performed between the present calculations and the available theoretical and experimental results.A good agreement can be found at the positions,strengths and profiles of the photoionization cross sections,especially with experimental spectrum.
