Theoretical study on the 4d9-4d85p transition in Xe9+

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.
