Özet

In this study, we aimed to determine coherent to Compton scattering differential cross section ratios of some inorganic materials (BaSO4, CaF2, Mg2SiO4, MgSO4, and ZnSO4(7H(2)O)) for several scattering angles (95 degrees, 105 degrees, 115 degrees, 125 degrees, and 135 degrees). Coherent to Compton scattering differential cross section ratios were investigated experimentally by using an HPGe detector, which has a resolution of 199.6 eV at the 5.9 keV. The samples were excited with 59.54 keV gamma rays emitted from Am-241 point source. The intensity ratios were corrected due to the photopeak efficiency of the gamma detector and absorption of photons in the target and air. It is observed that coherent to Compton scattering differential cross section ratios decrease with increasing scattering angle.
