Polarization dependence of the electron photoemission from the W(110)-Ba system at submonolayer coverages
Benemanskaya G. V., Lapushkin M. N.
The dependence of the integral photoelectron emission current of the (110)W face on the degree of the submonolayer coverage by barium is found to be quite different for s and ρ polarizations of visible exciting light. The difference is explained on the basis that the /?-polarized light excites emission from a band of surface electron states induced by the adsorption of barium.
