Annual Meeting of the ErUM-FSP APPA 2026

Using the electron-ion crossed-beams technique, we have measured absolute cross sections for electron impact single ionization of Xe$^{12+}$ and Xe$^{13+}$ ions, and double ionization of Xe$^{12+}$, Xe$^{13+}$ and Xe$^{14+}$ ions. In addition we have performed corresponding calculations using a hybrid level-to-level and subconfiguration-average distorted wave approach. We find excellent agreement between our experimental and theoretical data except near the double-ionization threshold.
