“…Measurements on He-Cu(110) revealed that exposure to hydrogen at room temperature reduces the surface Debye temperature by 50 K, which was interpreted as evidence for a reduction of the binding of the Cu atoms in the top layer (Miyake et al 1997). Eikonal calculations for an oscillating soft wall were reported by Mahale et al (1987) and applied to the scattering of He from noble gas adlayers. A theoretical study of the scattering of He atoms by a dilute adlayer having a dispersionless Einstein mode has been performed by Manson (1988).…”

Atomic beam techniques are presently being used in many branches of surface physics such as studies of the particle-surface physisorption potential, surface structure, surface phonons, nucleation and growth on metal and insulator surfaces, surface diffusion and accommodation and sticking of molecules. This review concentrates on diffractive phenomena from surfaces, which up to now were investigated mainly with helium. The theoretical background for diffraction calculations is outlined and representative examples of different applications are given. The main subjects covered are: structural determinations of chemisorbed and physisorbed systems, investigations of disordered surfaces, selective adsorption resonances, diffusion and nucleation studies and investigations of growth and phase transitions on surfaces. Diffraction results obtained with Ne, Ar, H 2 and D 2 are also summarized.
