TL;DRAbstract
The layer doubling method of dynamic calculation of Low Energy Electron Diffraction is introduced. It was used to analyse the reconstruction of Cu(110)-(l×2) surface induced by adsorption of alkali metals. The result shows that missing row model with top layer spacing contracted to 1.13? is the most reliable structure.
