Phys. Rev. A 75, 041201(R) (2007) [4 pages]Effect of giant plasmon excitations in single and double ionization of C60 in fast heavy-ion collisions
Single and multiple ionization of C60 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 (qp) 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 qp dependence for the single- and-double-ionization cross sections. But the same model deviates for triple and quadruple ionizations. © 2007 The American Physical Society URL:
