Spin-polarized low-energy electron diffraction (LEED) rotation curves measured with 30 to 80eV electrons scattered from a W(110) surface have been analysed with calculations using a relativistic multiple scattering theory, where quantitative reliability factors (R-factors) have been used to find the best fit between theory and experiment. The Zanazzi-Jona R-factor was used for intensity data, and...
It is shown that the electronic friction between a metallic surface and an open-shell atom or molecule moving perpendicularly to it can be substantially enhanced under experimentally interesting conditions due to the involvement of the Kondo or correlated mixed-valent state. The region of large friction is shifted from the point where the adsorbate resonance crosses the Fermi level to the point where...
