Coadsorbate-induced enhancement in the photoemission intensity of alkali core levels
Date of Original Version
The interaction of oxygen and CO with the alkali Na was studied with core level photoemission using synchrotron radiation. We observed intensity increases in the Na2p core level by a factor of 1.5-2 for the systems O2/Na/Ni(111), CO/Na/Ni(111), O2/Na/Cu(110) and O2/Na/Cu(111). These enhancements were more or less independent of substrate, coadsorbate and alkali precoverage. We examine several models to explain these observations. © 1993.
