Semiclassical formalism in ion-surface capture at high energies

The electron-capture process from the free-electron gas of a solid by heavy ions at grazing collisions is studied using the first Born approximation. A proper semiclassical expression is derived from the formal quantum treatment by introducing a classical trajectory to describe the movement of the p...
