Dielectronic recombination coefficients for ground-state ions of the Ne isoelectronic sequence have been calculated for seven ions, with atomic number 18< or =Z-italic< or =54, in the isolated resonance approximation, for temperatures in the range 0.2< or =T-italic< or =6 keV. The Auger and radiative rates of each doubly excited state were evaluated explicitly by using the multiconfiguration Dirac-Fock model. The calculations were performed with intermediate coupling. The effect of the configuration interaction was also included for the low-lying doubly excited states. The effect of Coster-Kronig-type transitions on the dielectronic rate coefficients has been found to be very significant for low-Z-italic ions. However, it is quite small for medium and heavy ions. The effect of relativity on the total dielec- tronic coefficient and dielectronic satellite spectra is also discussed.
