THE MOMENTS METHOD USED TO DETERMINE THE ENERGY ALBEDO OF GAMMA RAYS FROM CESIUM-137 IMPINGING ON ALUMINUM AND IRON BARRIERS,
Abstract
The moments method, as outlined by Spencer and Fano, was used to calculate the differential angular energy distributions of gamma ray fluxes backscattered from semi-infinite media. A plane normal source is simulated in the calculation. The data in this report are specifically for the angular energy distributions of .662 MeV gamma rays from Cs137 backscattered from semi-infinite media of aluminum and iron. The angles of detection are 110, 120, 130, 140, 150, and 160 degrees. The data presented in tabular form. A graphical comparison is also shown between results from an albedo experiment and the moments method. All of the moments method data were obtained from a computer program developed at NRDL using moments generated at the National Bureau of Standards. (Author)
