Abstract
We present first results of simulations for the neutralization and rel axation of multiply charged O-q+ ions in grazing incidence collisions with a gold surface. The simulation treats the direct quasi-resonant c harge transfer into the L shell of the projectile within the over-the- barrier model. The speed of neutralization is significantly enhanced b y the upward shift of energy levels at the surface due to dynamical sc reening. We find complete relaxation, neutralization, and negative ion formations within the available interaction time of a few times 10(-1 4) s in agreement with experiment.
