The characterisation of gamma photon incoherent scattering on free and binding electrons by Compton spectroscopy

International Journal of Nuclear Energy Science and Technology (IJNEST), Vol. 4, No. 3, 2009

Abstract: The incoherent scattering of 661.6 keV gamma rays in a wide range of atomic numbers was studied for ₆C, ₁₃Al, ₂₆Fe, ₂₉Cu, ₄₇Ag, ₄₈Cd and ₈₂Pb. It was shown that for heavy elements, the scattering on binding electrons is important. Meanwhile, for light elements, the scattering on free electrons is prominent. The differential Compton scattering cross-section as well as the incoherent scattering functions S (E, θ, Z) of atomic number Z for the studied subject was defined by the exponential saturated functions of the energy transfer model. The experimental values agree with the theoretical ones within experimental errors.
