Abstract:
Charge exchange properties of high first ionization potential atoms through thin carbon
foils are discussed in the context of
charge transfer models. A model is presented in which the charge state equilibirum within the solid
is explained by the overlap of the atomic and the solid state electron wave functions
in k space. Outside the solid, near surface, charge exchange occurs by
tunneling of electrons between the carbon surface and the exiting projectile.
