摘要：

Ionization and fragmentation have been measured for C-60 molecules bombarded in the vapor phase by Xe35+ and Xe13+ ions with energies in the range 420-625 MeV. The CM energies exceeded those used in previous studies by several orders of magnitude. We present the observed mass distribution of positively charged fragments together with a theoretical model indicating that the total interaction cross section contains roughly equal contributions from (a) excitation of the giant plasmon resonance, and (b) large-energy-transfer processes that lead to multiple fragmentation of the molecule.
