    Asymmetry of the Scattering of Polarized Electrons by Polycrystalline Gold
    (Addis Ababa, 1993-10) Neway, Bereket; Mishin, A .n. (PhD)
    The fundamental concepts of polarized electrons a nd t he mathmatical formulations of the scattering o f these e l ectrons from spinnless atoms are reviewed. The Theoretical investigations were made of the asymmetry of the sca ttering on the su rface of polycrystalli ne gold . Atomic data for a single s cattering process were use4 to calculate asymmetry and intensity as a funot~~ • • ~ scattering angle for multiple collisi ons . The specific i nflue nce of a so li d was taken in t o accou nt .
