Abstract
Angular differential number and energy albedo were measured at a scattering angle of 60° for narrow beam of 137Cs gamma rays normally incident on finite thickness scattering media of various atomic numbers. Measurements were made using a collimated 3 cm3 Ge(Li) detector with suitable electronics and a 400 channel pulse-height analyzer. The calculation of the energy spectrum of the scattered photons was carried out by using a response matrix with 51 energy intervals over the range 0·04−0·3 MeV.
