Determination of coherent/compton differential cross-section of some elements at different scattering angles

In this study, coherent/Compton differential cross section ratios (dσcoherent/dσCompton) of Uranium, Lead, Hafnium and Samarium elements were calculated at scattering angles of 85°, 95°, 105°, 115°, 125° and 135. The samples were irradiated by 59,54 keV energy photons emitted from on Am-241 radioctive source.The scattering photons measured using a HPGe detector with a resolution of 199,6 eV at 5,9 keV. The attenuation factor of air between the detector and samples (βγa), the sample's absorption factor for photons scattered from the sample (βγt) and the photopeak efficiency of detector for Compton and coherent energies have been performed for experimental calculations.The experimental results were compared with the theoretical results obtained with relativistic form factor theory, non-relativistic form factor theory and modified form factor theory. It was observed that the ratio of dσcoherent/dσCompton for each element decreased with increasing scattering angle.
