Scattering of Molecular Hydrogen and Its Isotopes from Crystal Surfaces.

Abstract

Molecular beam scattering of a thermal beam of H2 from vacuum cleaved (001) surfaces of MgO and LiF, and (111) surfaces of CaF2 and BaF2 has been examined. The scattering of He, D2 and HD from MgO (001) has also been investigated. The angular distribution of scattered flux indicates strong molecular diffraction from these surfaces. These results indicate that the surface structures of the crystals agree with those of the corresponding bulk planes. In addition to elastic diffraction maxima, strong extra peaks have been observed for hydrogen and its isotopes.
