Electron Impact Ionization of Xenon Atomic Ions

Excitation-autoionization features are studied in electron collisions with low-charged atomic ions in the Xenon isonuclear sequence. Calculations are made using semi-relativistic multi-configuration distorted-wave codes recently adapted for massively parallel computers. Theoretical predictions are compared with recent crossed-beams experiments for Xe$^+$ through to Xe$^{10+}$. The studies are extended to higher charged atomic ions of Xenon to map out the influence of radiation damping on excitation-autoionization features.
