Charge transfer collisions between fullerenes: C-60(3+)+C-60

Charge transfer collisions between C-60(3+) and C-60 are studied for collision energies between 400 and 3600 eV. Single and double electron transfers are observed, both occuring under single collision conditions. Absolute charge transfer cross sections are determined as a function of collision energy. The cross section for single electron capture of approx. 300 Angstrom(2) is about two times larger than that for double electron transfer. For both processes the cross section increases slightly with increasing collision energy.
