摘要：

Intensity and polarization spectra of the specular beam in spin-polarized low-energy electron diffraction (SPLEED) from Pb(110) have been measured - using a polarized-electron gun - and calculated by means of a fully relativistic multiple scattering formalism. Comparison between experiment and theory supports multilayer relaxation. At very low energy, surface barrier resonances in the spin-asymmetry spectra were observed and theoretically reproduced. Non-spherical contributions to the crystal-atom potential are visible in the theoretical results but smaller than remaining discrepancies with the experimental data. © 1990.
