Description
Excitation-autoionization contributions to the electron-impact ionization of Fe/sup 5+/, Fe/sup 6+/, Fe/sup 9+/, Fe/sup 11+/, and Fe/sup 13+/ are calculated in the distorted-wave approximation. Calculations for Fe/sup 5+/ which include only excitations from the 3p63d3 ground configuration agree well with the experimental crossed beams measurements of Gregory et al. [preceding paper, Phys. Rev. A 34, 3657 (1986)]. For Fe/sup 6+/ the agreement between theory and experiment is also good. Calculations for Fe/sup 9+/ are in reasonable agreement with experiment when only excitations from extremely metastable states of the 3p43d excited configuration are included. Theoretical predictions for Fe/sup 11+/ and Fe/sup 13+/ are based on ground-configuration excitations and detailed branching-ratio calculations. Excitation-auto- ionization contributions in Fe/sup 13+/ are found to enhance the total ionization cross section by a factor of 2 near threshold
