|Abstract:||The coherent (Rayleigh) to incoherent (Compton) scattering cross-section ratio of elements in the range 6 ≤ Z ≤ 82 for 59.54 keV gamma photons,have been measured. An HPGe gamma detector, placed at 90° to the incident beam, detects gamma photons scattered from the target under investigation. The intensity ratio of Rayleigh to Compton scattered peaks observed in the recorded spectra, corrected for photo-peak efficiency of gamma detector and absorption of photons in the target and air, along with the other required parameters provides differential cross-sections ratio for Rayleigh to Compton scattering. The measured values of cross-section ratio are found to agree with theory for low Z elements, but deviate from theory for high Z elements.|
