摘要：

Single and multiple ionization of C-60 in collisions with highly charged fast oxygen ions have been studied using the recoil-ion time-of-flight technique. The dependence of multiple-ionization cross sections on projectile charge state (q(p)) was found to be drastically different from those for an atomic target, such as Ne. A model based on the giant dipole plasmon resonance explains quite well the observed q(p) dependence for the single- and-double-ionization cross sections. But the same model deviates for triple and quadruple ionizations.
