Excitation-autoionization contributions to electron-impact ionization are calculated for several atomic ions in the cadmium isoelectronic sequence. We calculate excitation cross sections in the distorted-wave approximation and compare them in one case to a calculation in the close-coupling approximation. We focus attention on the 4d/sup 10/5s/sup 2/..-->..4d/sup 9/5s/sup 2/nf inner-shell excitations in In/sup +/, Sb/sup 3 +/, and Xe/sup 6 +/. Hartree-Fock atomic structure calculations for the 4d/sup 9/5s/sup 2/nf configurations are found to be highly term dependent. Thus our predictions for the total ionization cross section from the 5s subshell for these ions exhibit strong target term dependence. Our Xe/sup 6 +/ results are found to be in excellent agreement with the recent experimental crossed-beam measurements of Gregory and Crandall.
