Ab initio calculations of the rate coefficients for dielectronic recombination from Felike Au53+ to Galike Au48+ ions are performed based on Cowan's quasirelativistic multiconfiguration HartreeFockRelativistic code and distorted wave approaches. A large number of single excited states and doublyexcited states are included in the present calculation. Because of the extensive distribution of autoionization state energy levels and complicated cascade effects, the dielectronic recombination rate coefficients at higher Z are different from those at lower Z's. The results indicate that the error between our work and other theories is less then 10% in the diagnosed electron temperature and density. It is feasible to simulate the average ionized state and charge state distributions in a well characterized highly ionized Au plasma.
