Predictions of characteristics of prompt-fission γ -ray spectra from the n + ~(238)U reaction up to E_n = 20 MeV

摘要

Systematics from 2001, describing prompt-fission γ -ray spectra (PFGS) characteristics as a function of mass and atomic number of the fissioning system, was revisited and parameters were revised, based on recent experimental results.Although originally expressed for spontaneous and thermal-neutron induced fission, validity for fast neutrons was assumed and applied to predict PFGS characteristics for the reaction n + ~(238)U up to incident neutron energies of E_n= 20 MeV. The results from this work are in good agreement with corresponding results from both model calculations and experiments.
