Recent advances in the comparison of matter- and antimatter-atom collisions

The relatively recent advent of low energy antimatter projectiles has spurred a rapid advance in the comparison of matter- and antimatter-atom collisions. These experimental studies have in turn stimulated a great deal of theoretical effort to explain their results, and together both theory and experiment have shed new light on the dynamics of ion-atom collisions. The authors review these developments with particular emphasis on the processes of ionization and charge transfer.
