Molecular view of charge exchange in ion–C60 collisions

Abstract We present a theoretical study of charge transfer in H++C60 and He2++C60 collisions using an extension of the molecular time‐dependent method of ion–atom collisions. Energy‐correlation diagrams have been evaluated for the corresponding (C60–H)+ and (C60–He)2+ quasi‐molecules. Single and double charge‐transfer cross sections in C60+He2+ 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. © 2001 John Wiley & Sons, Inc. Int J Quantum Chem, 2001
