Incoherent scattering of 320 keV photons by K-shell electrons

The differential incoherent scattering cross sections of 320 keV photons by K-shell electrons of lead, tantalum and samarium are experimentally determined employing a fast-slow coincidence scintillation spectrometer by the degraded photon K X-ray coincidence technique at angles of scattering 45°, 60°, 90° and 110°. The results are compared with the computed values and the trends of the incoherent scattering function are discussed.
