Abstract
We report electron impact ionization cross section measurements for electron impact single ionization of Fe12+ forming Fe13+ and electron impact double ionization of Fe12+ forming Fe14+. These are the first electron impact ionization data for any Si-like ion uncontaminated by an unknown metastable fraction. Recent distorted wave calculations agree with our single ionization results to within similar to 15%. Double ionization is dominated by inner shell ionization of a 2l electron resulting in autoionization of a second electron as the inner shell hole is filled.
