Electron-impact ionization of Fe3+

Abstract

Synopsis Electron-impact ionization cross sections are studied for levels of the ground and first excited con-figurations of the Fe3+ ion. Convergence for the excitation-autoionization cross sections due to excitations to the high-nl shells is investigated. Single configuration and configuration interaction methods are used in the study. Scaling is applied to the distorted wave cross sections of the excitation-autoionization and collisional ionization processes.
