Dielectronic recombination (DR) coefficients for the ground-state ion of Ni-like /sub 64/Gd have been calculated in the isolated-resonance approximation for temperatures in the range of 0.05less than or equal toTless than or equal to3 keV. The Auger and radiative rates of each doubly excited state were evaluated explicitly by using the multiconfiguration Dirac-Fock model. The calculations were carried out in the intermediate coupling. The effect of the configuration interaction was also included for the low-lying doubly excited states. The intermediate autoionizing states included in the present work are the states from the 3d/sup -1/4lnl' (nless than or equal to10), 3p/sup -1/4lnl' (nless than or equal to5), and 3s/sup -1/4lnl' (nless than or equal to5) configurations. The dielectronic recombination coefficients for Ni-like /sub 64/Gd from the present calculations are 1.33 x 10/sup -10/ and 1.08 x 10/sup -10/ cm/sup 3//sec for T = 500 and 800 eV, respectively. The semiempirical Burgess-Merts formula has been found to overestimate the dielectronic recombination coefficients for the Ni-like /sub 64/Gd by a factor of 5 for Tgreater than or equal to250 eV.
