This talk will address interactions of slow highly charged ions with metal and insulator surfaces, leading to the formation of unstable, multiply excited projectiles. We have simulated the forma- tion and decay of such hollow ions on the basis of a refined classical over-barrier model. These simulations include the full trajectory of the projectile and allow for the simultaneous evaluation of projectile kinetic energy gains, final charge-state distributions, and emitted Auger electron yields.
