Abstract : This work examines Environmental effects, which do not arise from alteration of the excited-state lifetime, but rather from. (1) the image charge induced in the metal substrate, (2) adsorbate-adsorbate interactions which reduce the symmetry and hence cause certain selection rules to breakdown, and (3) coherent scattering of electrons in the substrate. Review previously were reported ESD yields of 0- for 02 condensed on polycrystalline Pt in the electron energy range 0 to 40 eV. Keywords: Electron stimulated desorption, Image charge, Coherent scattering.
