Popis: The resonance-enhanced multiphoton ionization (REMPI) technique has been used to probe the dynamics of NO scattering from oxygen-covered Si(100) as a function of incident beam energy E i and incident angle θi. A direct inelastic scattering process as well as a trapping-desorption process was observed to occur even for the lowest incident energy available in our apparatus, 0.09 eV. Considerable loss in the peak velocity was found to be E i-dependent for the direct inelastic component scattered at the specular angle. The angular width of the scattering lobe increased with increasing E i. These facts are qualitatively explained in terms of the surface corrugation.
