Abstract
Single-electron capture from He to Ne6+ at 2.0 keV projectile energy is studied using the atomic expansion close-coupling approach.The possibility of collision-induced core excitation is investigated and found to be of little importance in a time-dependent model treatment in contrast to multichannel Landau-Zener calculations. An important reason for the discrepancy between Landau-Zener calculations and close-coupling calculations is the effect of rotational coupling, which is responsible for about 50% of the cross section for the present system. Based on the time-dependent approach the experimental energy gain spectrum can be identified as capture to the 3d level.Keywords
