Dielectronic Recombination of Ni-Like Gold Ion Through the Cu-Like 3d^94ln＇l＇ （n＇= 4, 5） Configurations

Ab initio calculations of dielectronic recombination (DR) rate coefficients from the ground state of Ni-like A u ion through the Cu-like 3d^94ln‘l‘ (n‘= 4, 5) configurations have been performed by using a relativistic atomic code FAC with configuration interaction. The DR rate coefficients through the 3d^94l5f5/2 and 3d^94l5f7/2 configurations are evaluated separately. The contributions from resonant and nonresonant radiative stabilizing transitions to the total rate coefficients are distinguished and discussed. The decays to autoionizing levels followed by radiative cascades are included in the calculation.
