Abstract:
Charge exchange properties of H atoms passing through thin carbon foils
at incident energies from 0.5 to 120 keV/u are discussed in the context
of charge transfer models. A model is presented in which the charge
state equilibrium in the solid is explained by the overlap of the
atomic and the solid-state electron wave functions in k space. Outside
the solid, near the surface, charge exchange occurs by tunneling of
electrons between the carbon surface and the exiting projectile. Review
