Angular Distributions of Secondary Electrons Emitted from the Polycrystalline Silver

The angular distributions of secondary electrons (including Auger electrons) of different energies emitted from polycrystalline silver bombarded with primary electrons (E$\text{}_{p}$ = 1000 and 2500 eV) were measured with a RFA analyzer equipped with an additional collector (acceptance angle ≈ 4°). Additionally, the angular distributions of primary electrons of different energies elastically backscattered from the same sample were also investigated by means of a specially constructed rotable RFA analyzer equipped with a channeltron. The results obtained show the cosine distribution of secondary and Auger electrons emitted as shown previously in the literature. The angular distributions of electrons backscattered elastically depend on electron energy and are in good agreement with theoretical calculations (Monte Carlo simulation of primary electrons trajectories in solids) proposed by Jabłoński.
