Abstract
We simulated the population dynamics of target and projectile levels during the interaction of slow, highly charged ions and C60. Our investigation is based on a semiclassical over-barrier description of long-range charge exchange and a spherical model for the C60 cluster. It includes the transient formation of hollow atoms and relaxation of the projectile due to Auger cascades. As a first application, we consider slow Ar8+ projectiles and give estimates for the occupation changes of all coupled target and projectile levels, charge-state evolutions and energy-resolved spectra of emitted Auger electrons. Our results are in satisfactory agreement with recent experimental data.
