Electron Diffraction Study of Sodium Bromide Thin Films

Data from an electron diffraction measurement of integrated intensities of Debye reflections for polycrystalline sodium bromide films are used to construct curves of the electron atomic scattering factors of Na and Br. An approximation is given of experimental f curves by analytical expressions obtained in the Slater approximation. The parameters of the approximation are used to calculate the charge on the atoms and also to determine the potential distribution in the sodium bromide unit cell.
