Abstract
A LEED analysis of a clean Mo(110) surface was performed at room temperature. A detailed examination was made of the influence of non-structural parameters including the surface Debye temperature, the correlation-exchange contribution to the ion-core scattering potential and energy dependence of the effective inner potential. Comparison of experimental and theoretical results was made quantitatively and, after optimisation of the relevant theoretical parameters, a value for the surface interlayer spacing of 2.19+or-0.04 AA was obtained; this represents a contraction of about 1.6+or-2% from the bulk interlayer spacing.
