摘要
Fully relativistic, ab initio calculations of the rate of dielectronic recombination (DR) have been performed for fluorinelike Mo33+ to magnesiumlike Mo30+ and chlorinelike Mo25+ and argonlike Mo24+. Calculations of the rate of excitation autoionization (EA) have been performed for neonlike Mo32+ to aluminumlike Mo29+ and argonlike Mo24+ and potassiumlike Mo23+. 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 3s(2)3p(k) (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.
