“…The surface roughness of silver films was determined by scattered light intensity (67). The adsorption of Oxygen on the crystal faces of silver has been followed by LEED (235,508,509), AES (235,508), ISS (235), FEM (137), and FIM (523). A detailed study of silver surfaces of films prepared in a number of ambients correlated optical properties with surface composition as determined by AES (467), and oxidation of polycrystalline metal was followed by EPR (124).…”
