摘要：

We present first results of simulations for the neutralization and relaxation of multiply charged O-q+ ions in grazing incidence collisions with a gold surface. The simulation treats the direct quasi-resonant charge transfer into the L shell of the projectile within the over-the-barrier model. The speed of neutralization is significantly enhanced by the upward shift of energy levels at the surface due to dynamical screening. We find complete relaxation, neutralization, and negative ion formations within the available interaction time of a few times 10(-14) s in agreement with experiment.
