Variation of electron energy and angular distributions has been studied as a function of column density by combining small-angle analytical treatment with large-angle Monte Carlo calculations. The distributions have been calculated for initial electron energy 300 keV and various incidence directions. Using these distributions and a Sauter bremsstrahlung cross-section differential in photon energy and emission angle, the X-ray energy and angular distributions for photon energies 10, 20, 50, 100, 150 and 200 keV are calculated. By taking the ratio of X-ray flux at 90 and 180, the anisotropy ratio A is computed as function of column density. Calculated anisotropy ratio compares well with ISEE-3 and PVO observations.
