Abstract : The computer code I-GAM calculates macroscopic cross sections for the production of gamma rays by neutron inelastic scatter. It does so by associating nuclear energy level excitation with energy deposited by neutrons undergoing inelastic scatter. Such energy deposition is described by a 99 fine group inelastic scatter array. The decay of excited levels is in conformance with nuclear level transition probabilities and produces photons of discrete energy which are combined in multigroup form. I-GAM calculates cross sections in up to 18 gamma ray broad groups and 22 neutron broad groups. Author)
