Abstract
Significant sharp enhancements(FWHM less than or equal to 0.5 eV) are observed in electron stimulated desorption O- yields, obtained from sm all quantities of CO2 physisorbed on thick rare gas substrate films. T he enhancements are positioned 0.3-0.4 eV below the lowest substrate e xciton energy, and are attributed to a coupling of the (electron plus exciton) core-excited anion resonances of the rare gas atoms to the di ssociative temporary molecular anion states of the co-adsorbed CO2 at the solid's surface. This causes a transfer of the charge and excitati on energy to the co-adsorbate.
