Resonance contributions to the electron-impact ionization of few-electron highly charged ions

Abstract
We present results for the electron-impact ionization of Li-like, Be-like, and B-like Fe, Kr, and Xe ions. We have included the contributions from direct ionization, excitation autoionization, and dielectronic-capture double autoionization in our calculations. We discuss isonuclear and isoelectronic trends for the various contributions, focusing on the resonance contributions in particular.
