摘要: 利用多组态Dirac-Fock(MCDF)方法，通过对Xe9+离子4d9-4d85p跃迁的系统计算，研究了电子相关效应对Xe9+离子4d9-4d85p跃迁的影响，给出了相应的跃迁能和辐射跃迁几率，并与最新的实验观测和其它理论计算结果进行了比较。计算结果表明：电子的关联效应显著。根据计算结果和实验结果的一致性和两个规范下所得的跃迁几率的一致性，可以认为本文的计算结果是可信的。Abstract: In the present work, the effects of correlation are systematically studied for the 4d9-4d85p transition of Xe9+ ion by using the multi-configuration Dirac-Fock method, and the results of the transition energies and probabilities are presented. Comparison with some existing experiments and theoretical calculations is made. It is found that the correlation effects are very important in this case. According to the very good agreement between our calculations and experimental results and the agreement between transition probabilities in Babushkin gauge and Coulomb gauge, the present results are reasonable.
