Abstract

A new method for monitoring the development of chemisorption processes on metallic surfaces (either single crystals or polycrystalline), is demonstrated. The method involves direct detection of metal vaporization by laser resonance ionization. It has a remarkably high sensitivity and selectivity for detecting vapor densities (of the order of a few atoms cm^-3) enabling vaporization measurements even at relatively low temperatures (about room temperature). This method is demonstrated for the case of room-temperature chemisorption of oxygen on polycrystalline magnesium. A random initial chemisorption stage followed by an island growth stage is seen to dominate the chemisorption process.
