Abstract
The intensity of electrons scattered by a metallic surface is considered in terms of the surface electron density modulated by lattice vibrations of atoms at the surface. The temperature dependence of thermal vibrations is determined on the basis of the pseudoharmonic approximation for the interatomic interaction. The pseudoharmonic method brings an essential correction to the temperature behaviour of the low energy electron intensity and it seems to be a very useful approach to the description of diffraction phenomena.
