Abstract : Atomic and molecular scattering from tungsten and platinum surfaces is discussed. The phenomenological regimes of quasi-elastic, inelastic and trapping dominated scattering are identified. The role of the strength of the surface periodicity in producing diffractive scattering is discussed and the extreme sensitivity of non-diffractive helium scattering to microscopic surface roughness is identified.
