Prompt gamma rays from the inelastic scattering of fission neutrons on samarium and dysprosium
Abstract Prompt gamma rays produced by inelastic scattering of fission neutrons on samarium and dysprosium were measured with the instrument FaNGaS (Fast Neutron-induced Gamma-ray Spectrometry) at Heinz Maier-Leibnitz Zentrum (MLZ). Relative intensities and production cross sections for 288 gamma lines (140 for samarium, 148 for dysprosium) were calculated considering interferences from radiative capture lines. Consistency with data obtained from irradiation with reactor fast neutrons was evaluated. Our results contribute to the expansion and the improvement of databases related to the interaction of fission neutrons with nuclei. The detection limits of samarium and dysprosium are estimated as 0.6 and 1.6 mg for a measuring time of 12 h.
