| Abstract |
: |
Absolute cross sections for electron impact single ionization of Kr/sup 10+/ and Kr/sup 11+/ ions and double ionization of Kr /sup q+/ (/b q/=8-13) have been measured in an animated crossed-electron ion beam experiment. Ionization thresholds corresponding to particular electron pairs and inner-shell electron ejection are estimated from a structure Hartree-Fock calculation. For double ionization, results show that, along the homonuclear sequence, direct double ionization is progressively overcome due to the increasing relative importance of direct /b L/-shell ionization followed by autoionization. The presence of ions in metastable states is observed for Kr/sup 8+/ and Kr/sup 9+/ contributing to direct and indirect processes. |
