Popis:	Previous works on Cl adsorption on Ag(111) showed that there are different stages of adsorption. We have supposed three main stages before the growth of a thick AgCl layer. These are labelled stages (a)-(c). We report on a characterization of the stage (c) structure with AES, HREELS, LEED, UPS, ISS and work-function changes. AES, HREELS, UPS and LEED show that the main feature of the stage (c) structure is the coexistence of Ag and AgCl crystallites on the surface. Additional details for the stage (c) structure revealed by HREELS and ISS are presented. The additional features are the presence of Ag defect sites and that the concentration of Cl on the Ag crystallites is less than full coverage.
