| 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.
