Molecular View of Charge Exchange in Ion-C_(60) Collisions

摘要

We present a theoretical study of charge transfer in H~+ + C_(60) and He~(2+)+C_(60) collisions using an extension of the molecular time-dependent method of ion-atom collisions. Energy-correlation diagrams have been evaluated for the corresponding (C_(60)-H)~+ and (C_(60)-He)~(2+) quasi-molecules. Single and double charge-transfer cross sections in C_(60)_He~(2+) collisions are reported for the first time. The results show that double charge-transfer cross sections are only one order of magnitude smaller than single charge-transfer cross sections.
