Abstract
Energy spectra of the three charge states and charge-state fractions of hydrogen and deuterium backscattered under ultrahigh-vacuum conditions from a polycrystalline clean gold surface are reported. The primary energy of the incident particles varies from 1 to 5 keV per atom. A comparison with measurements by different authors indicates a strong dependence of charge-state fractions on the cleanliness of the target material. No dependence on the primary energy of the impinging particles has been observed. The shape of the reported spectra indicates a high probability for destruction of negative ions near a solid surface.Keywords
