Electron-spin polarization in low-energy electron diffraction from tungsten (001)
Combined measurements in low-energy electron diffraction of both electron-spin polarization and intensity are described for beams from W(001). Polarization and intensity are determined in the energy range 20-150 eV for both the 10 and 11 beams at normal incidence and for the 00 beams at angles of incidence from 10/sup 0/ through 18/sup 0/ in 1/sup 0/ steps. Electron-spin polarizations in the range +60% - -80% are observed with polarization values highly dependence on both the energy and the angle of incidence of the primary electron beam. For the 00 beam at 11/sup 0/ angle of incidence and for the 10 beam at normal incidence, comparisons of the present intensity and polarization data with the results of recent theoretical calculations are encouraging with respect to gross features. 16 references, 13 figures.
