Adjustment of the parameters in the calculations of the γ-production data

The γ-production data are very important for the nuclear engineering, especially for the calculations of the radiation shielding. The γ-production data in the nuclear reactions induced by neutrons include the γ-production cross sections, the γ-energy spectra, the γ-multiplicities and the reaction cross sections of the (n,γ) and (n,xγ) reaction. Because of the differences of the γ production mechanisms in the statistical and non-statistical processes of the (n,γ) reactions, the adjustable parameters in the calculations are different. The basic principles of the parameter adjustment for different reactions in the calculations of the γ-production data are discussed
