Abstract

Helium atom diffraction yields a wealth of information complementary to that obtainable from other experimental surface sensitive techniques. Atomic He scattering is extremely sensitive to surface defects. Also time of flight measurements enable energy transfer processes to be studied. An analysis of the energy broadening in quasi-elastic scattering can yield information on surface diffusion coefficients and may also be used to investigate diffusion mechanisms. The paper reviews how intensities of both coherent and incoherent scattering can be employed to study the kinetics of ordering at surfaces.
