Angular and Intensity Distributions on Multiple Scattering of 662 keV Gamma Photons in Aluminium

Abstract:

This work studied about the angular and intensity distributions on multiple scattering gamma energy 662 keV, obtained from ¹³⁷Cs source. The gamma photons are incident on aluminium scatterer of varying thickness is studied experimentally in both the forward and backward hemispheres. The observed spectra recorded by a properly shielded NaI(Tl) scintillation detector. To extract the contribution of multiply scattered photons having same energy as in the singly scattered distribution from the measured spectra, a singly scattered distribution is reconstructed analytically. We observed that the number of multiply scattered photons also increases and saturates at a particular value of the scaterrer thickness and determined at different scattering angles.
