Abstract
Within a semiclassical overbarrier model for non-destructive, long-range charge exchange, the population dynamics of target and projectile levels, charge-state evolution and electron emission during the scattering of 50 keV N5+ ions on C60 are simulated. The model describes the transient formation of hollow projectiles due to resonant electron capture and Auger relaxation of the multiply excited projectiles. Estimates for total cross sections in charge-state-changing collisions and the deflection functions for the dynamical Coulomb trajectory are given. Evidence for a strong enhancement of the angle-differential scattering cross section is found and related to the dielectric response of the target.
