Abstract
The interaction of oxygen and CO with the alkali Na was studied with c ore level Photoemission using synchrotron radiation. We observed inten sity increases in the Na2p core level by a factor of 1.5-2 for the sys tems O2/Na/Ni(111), CO/Na/Ni(111), O2/Na/Cu(110) and O2/Na/Cu(111). Th ese enhancements were more or less independent of substrate, coadsorba te and alkali precoverage. We examine several models to explain these observations.
