Survival probability of an excited sputtered Al atom in the 4s2S1/2 state from a polycrystalline Al surface as a function of surface-oxygen coverage

Proton sputtering from polycrystalline Al surface interacting with highly charged ions at grazing incidence angle

“…3p 2 P 1/2,3/2 : 395.1 and 396.2 nm) lines. The intensity of photons emitted from the excited neutrals, which were sputtered from the surface, was strongly affected by the particles adsorbed on the surface [21]. Therefore, it was considered that surface diagnostics by optical spectroscopy is sensitive to the topmost layer or the adsorbed particles.…”
