Dielectronic Recombination of Ni-Like Gold Ion Through the Cu-Like 3d⁹4ln’l’(n’= 4,5) Configurations

Ab initio calculations of dielectronic recombination (DR) rate coefficients from the ground state of Ni-like Au ion through the Cu-like 3d⁹4ln’l’(n’= 4,5) configurations have been performed by using a relativistic atomic code FAC with configuration interaction. The DR rate coefficients through the 3d⁹4l5f_5/2 and 3d⁹4l5f_7/2 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.
