Abstract

During the perpendicular bombardment with 25 keV primary electrons the azimuthal and polar angular distribution are measured of those backscattered electrons which escape from the low index surfaces of a copper monocrystal. A movable electron spectrometer operates as a detector with the energy resolution of Δ__E__/E ≈ 10^−3^ and the angular resolution of Δθ = 0.5°. The observed angular distribution proves congruously with large angle Kikuchi reflection diagrams, the representation of which at metallic surfaces was successful as yet only for oblique incidence. The connection between escape direction and energy loss and also the influence of covering layers are investigated.
