K- And L-shell Resonant Transfer And Excitation In Ion-atom Collisions

Abstract

Recent experimental studies of resonant transfer and excitation (RTE) in ion-atom collisions are reviewed. In the RTE process correlated electron capture and projectile excitation occur together in a single encounter with a target atom. Measurements of Caq+ + H2 (q= 10-19) from 100 to 370 MeV establish the projectile charge-state dependence of K-shell RTE and provide a detailed test of the theory. Structure due to RTE is observed in the energy dependence of the total electron-capture cross sections for this collision system. A comparison of the Ca17++H2 data with previous results for Ca17++He demonstrates the effect of the target-electron momentum distribution on the RTE process. Studies of 230-610 MeV Nb31+ +H2 provide information about RTE involving projectile L-shell excitation. All the measurements are in reasonable agreement with theoretical calculations. © 1987.
