Abstract The rate coefficients for the dielectronic recombination of astrophysically abundant ions in the He, Li, Be, and Ne isoelectronic sequences are computed in the isolated resonance approximation. All important electric dipole radiative transitions are included, allowing for nondipole as well as dipole captures and autoionizing transitions. Radiative and autoionization rates are calculated from experimental oscillator strengths and energy level data whenever these are available, using approximations to reduce the complexity of the computation. An LS coupling scheme is adopted where the coupling of the captured electron is averaged over in the computations. The accurate determination of possible capture and decay channels makes it possible to compute dielectronic recombination rate coefficients which are a substantial improvement over the Burgess (1965) and Merts et al. (1980) method and previous work that neglect some transitions or employ configuration-averaged energies and decay rates.
