Measurements of the total molecular differential attenuation coefficients of some compounds for scattering of γ-rays

The differential attenuation coefficients for total scattering have been measured using the Si(Li) detector at photon excitation energy of 59.5 keV for Fe2O3, Y2O3, Nb2O5, SeO2, Sb2O5 and BaO compounds at seven angles ranging from 60° to 120° at intervals of 10°. The obtained results have been compared with relativistic and non-relativistic theoretical values.
