Abstract
The atomic scattering factors of fast electrons at zero angle of incidence of an electron beam, f el(0), are calculated for neutral atoms with Z = 1−54, using the mean-square radii of electron-density distributions in atoms and ions, derived on the basis of the Hartree-Fock wave functions. The values of f el(0) have been calculated for the first time for some positive and negative ions. The obtained values of f el(0) were used to determine the mean inner potentials V0 of metallic, covalent, and ionic crystals. The calculated values of V0 are compared with the experimental data in the literature. The values of V0 calculated for III–V and II–VI compounds are reported.
