Rapid evaluation for dielectronic recombination rate coefficients of the H-like isoelectronic sequence

In this paper we present a set of accurate formulae for rapid calculation of dielectronic recombination rate coefficients of H-like ions from Ne(Z = 10) to Ni(Z = 29) with the electron temperature range from 0.6 to 10 keV. This set of formulae are obtained by fitting directly the dielectronic recombination rate coefficients calculated on the basis of the intermediate-coupling multi-configuration Hartree-Fock model made by Karim and Bhalla. The dielectronic recombination rate coefficients from these formulae are in close agreement with the original results of Karim et al. The errors are generally less than 0.1%. The results are also compared with the ones obtained by a set of new rate formulae developed by Hahn. These formulae can be used for generating dielectronic recombination rate coefficients of some H-like ions where the explicit calculations are unavailable. The detailed results are tabulated and discussed. Copyright (C) 1996 Elsevier Science Ltd
