Determination of the Adsorption Site by Low-Energy Electron Diffraction for Iodine on Silver (111)

Abstract
Iodine adsorbing on a silver (111) surface forms a (3×3)30° structure. The position of the adsorbed atoms within the unit cell of the surface layer has been determined by comparison of the measured curves of intensity versus energy of several low-energy electron diffraction spots with dynamical model calculations.
