Abstract
Fully relativistic, ab initio calculations of the rate of dielectronic recombination (DR) have been performed for fluorinelike [Formula Presented] to magnesiumlike [Formula Presented] and chlorinelike [Formula Presented] and argonlike [Formula Presented]. Calculations of the rate of excitation autoionization (EA) have been performed for neonlike [Formula Presented] to aluminumlike [Formula Presented] and argonlike [Formula Presented] and potassiumlike [Formula Presented]. The detailed calculations of the atomic structure and rate coefficients for charge states in these groups allow interpolation of the DR and EA rates for the more complex ions having 3[Formula Presented]3[Formula Presented] (k=1–4 for DR and k=2–5 for EA) ground states. The calculations for DR are broken up by different classes of excitation channels; simple, analytic formulas are then fit to the calculations. The effects of configuration interaction on the rates of DR and EA have been studied in detail and are found to have a slight effect on only a small class of the Auger rates needed for the present work. Radiative transitions between energy levels in the continuum are investigated and found to have a moderate effect on the DR rates and a small effect on the EA rates of the ions in this paper.
