    Asymmetry of the Scattering of Polarized Electrons by Polycrystalline Gold
    (Addis Ababa University, 1993-10) Neway, Berket
    The fundamental concepts of polarized electrons and the mathmatical formulations of the scattering of these electrons from spinnless atoms are reviewed. The Theoretical investigations were made of the'asymmetry of the scattering on the surface of Polycrystalline Gold. Atomic data for a single scattering process were used to Calculate Asymmetry and intensity as a functions of the scattering angle for multiple collisions. The specific influence of a solid was taken into account. The asymmetry of the scattered electrons into a wide solid angle was calculated and a comparison with some experimental data for the scattering of polarized electrons of energy Ep from 100 to 500 eV was made. Satisfactory agreement ahs obtained beween the , " calculated and experimental results
