Abstract
The first low-energy-electron-diffraction measurements using a polarized incident electron beam are reported and compared to measurements where an unpolarized incident beam is analyzed after scattering. Whereas, because of multiple scattering, equivalence of the two measurements is not expected in general, excellent agreement is obtained for specular scattering in the (010) plane from W(100). A theoretical argument is presented for the case where the scattering plane is a mirror-symmetry plane of the crystal.Keywords
