Inelastic neutron scattering and prompt fission neutron spectra for 237Np

Analysis of prompt fission neutron spectrum and multiplicity for 237 Np(n, f) in the frame of multi-modal Los Alamos model

“…The total prompt neutron spectra calculated from expressions (1) and ( 2) for E n = 0.52 and 4.9 MeV are shown in Figs. 6(a) and 6(b), respectively, together with experimental data given by Kornilov et al [23] and Trufanov et al [24] The Maxwellian spectra are also shown in the figures. It can be seen that the multimodal calculations reproduce the experimental data and are in better agreement with the experimental data than the Maxwellian spectrum.…”

Digital spectrometer for prompt fission neutron spectrum measurements

“…The intrinsic detection efficiency of neutron detector has been obtained on the basis of the standard spectrum of 252 Cf prompt fission neutrons taken from ENDF-BVII.1 library and the spectrum obtained experimentally [3,4]. The obtained results are shown in Fig.…”

Current Inconsistencies in 238Pu, 241,243Am and 242Cm Evaluations and their Impact on Uncertainties

“…These approaches were later supported by the measurement of prompt fission neutron spectra for 237 Np(n,F) by Taieb et al [39]. In view of recent measurements of 237 Np(n,F) by Tovesson et al [40,41], 237 Np(n,γ) by Esch et al [42] and 237 Np(n,n') by Kornilov et al [43] a consistent description of partial compound nucleus cross sections should be attempted. Such results might have important implications for increasing the reliability of other odd-Z, and even-N target nuclides.…”
