Transfer and excitation with heavy projectiles and targets

Abstract

It has been shown that projectile excitation and electron capture can occur together in a single encounter between an ion projectile and a target electron. The capture and excitation events can be correlated (Resonant Transfer and Excitation (RTE)) or uncorrelated (Nonresonant Transfer and Excitation (NTE) and Uncorrelated Transfer and Excitation (UTE)). In collisions of intermediate Z projectiles with H2 and He there is now generally good agreement between experiment and theory but a few existing discrepancies are discussed. There is as yet no theoretical work for heavy projectiles but experimental work is now underway. In heavy targets it appears that the uncorrelated process dominate over RTE.
