摘要

The gamma photons continue to soften in energy as the number of scatterings increases in the target having finite dimensions both in depth and lateral dimensions.The number of multiply scattered photons increases with an increase in target thickness,and saturates at a particular value of the target thickness known as saturation thickness(depth).The present measurements are carried out to study the energy dependence of saturation thickness of multiply scattered gamma photons from targets of various thicknesses.The scattered photons are detected by a properly shielded Nal(Tl)gamma ray detector placed at 90° to the incident beam.We observe that the saturation thickness increases with increasing incident gamma photon energy.Monte Carlo calculations based upon the package developed by Bauer and Pattison [Compton scattering experiments at the HMI(1981),HMI-B 364,pp.1-106] support the present experimental results.
