Abstract

Ion fractions of Ne⁺ and Ar⁺ in the scattered flux and of H⁺, O⁺, and Mg⁺ in the directly recoiled flux have been determined during Ne⁺, Ar⁺, and Ar²⁺ bombardment of clean, oxidized and hydroxylated magnesium surfaces. The VUV photons emitted during bombardment of clean Mg have been analyzed. The extraordinarly large ion fractions of Ne⁺ and O⁺, the sensitivity of the ion fractions to adsorbates, and the emitted photons are analyzed in terms of an ion-surface charge-exchange mechanism. The direct recoil measurements are capable of detecting the chemisorbed oxygen-oxide phase transformation on the magnesium surface.
