    • Abstract


      In this paper, we present the design and construction of a 20 Ci γ-ray Compton spectrometer that employs a137 Cs source with a strong line at 661.65 keV. The total resolution of the spectrometer in momentum scale is 0.40 a.u., which is much better than the conventional241Am Compton spectrometers. The in-house137Cs spectrometer is very useful for the measurement of momentum densities of heavy materials. The performance of the machine is assessed using aluminum, terbium and mercury samples and the experimental data from comparable apparatus.
