Abstract
Inelastic electron scattering spectroscopy has been used to measure energy-gain as well as energy-loss transitions of oxygen chemisorbed on the Ru(001) surface. The relative intensity of the energy-gain to the energy-loss transition was found to follow the expected Boltzmann distribution. The intensities of the inelastic peaks relative to the elastic peak were observed to increase with temperature. The temperature dependence and sources of experimental error are explained within the context of an approximate theory for the scattering of electrons from adsorbates on metal surfaces.
