Show affiliationsLow-energy spin-polarized two-electron spectroscopy in reflection geometry has been applied for studying spin-dependent electron scattering dynamics and electronic structure of clean and oxygen covered W(110) surface. Strong spin-orbit asymmetry was observed in the energy sharing spectra of clean tungsten for binding energy close to the Fermi level. This asymmetry was suppressed by oxygen adsorption although the bonding 2p - state is located 6 eV below the Fermi level. It indicates an extended influence of the oxygen adsorption on the electronic structure of the substrate and the surface barrier.
