Electronic Surface Resonance Enhancement of Vibrational Loss Intensities. Their effect on the impact energy dependence of the syumuetric stretch-vibration excitation cross-section of chemisorbed hydrogen is to produce resonance enhancement. Results are presented for both the low coverage c(2 × 2)H and high coverage p(l × 1)H chemisorbed layers. The energies of these res

Electronic Surface Resonance Enhancement of Vibrational Loss Intensitiesance intensity is found only for energies corresponding to energy gaps in the surface projection of bulk states. The effect on adsorbate vibrational selection rules is discussed in terms of the degree to which the resonance electron density overlaps the short range scattering potential of the vibrating atoms.
