摘　　要：The two-dimensional autocorrelation function of island separations for commensurately adsorbed overlayers is evaluated and used to calculate the angular profiles of the diffracted beams from arbitrary distribution of overlayer islands.Model calculations are made for a realistic surface.The results are compared to the low energy electron diffraction(LEED)measurement of O/W(112)system and quantitative structural information on the distribution of islands for overlayers is then extracted.
