The surface of Si and thin layers of Pd2Si on Si have been studied by low-energy He+ ion scattering. The occurrence of the observed low-energy tails is attributed to reionization at the surface of He neutrals scattered from subsurface layers. It is shown that the tails provide valuable in-depth information.
