Status of ENDF/B-V neutron emission spectra induced by 14-MeV neutrons. [Partial and total spectra, cross sections, graphs]

PDF Version Also Available for Download.

Description

ENDF/B-V neutron emission spectra induced by 14.6 MeV incident neutrons are graphically compared with experimental data. The elements selected for the comparisons include Na, Mg, Al, Si, Ca, Ti, V, Cr, Fe, Ni, Cu, Nb, W, and Pb. Partial as well as total spectra from the ENDF/B-V evaluations are shown in each graph, while experimental data were available only for the total. Energy distribution laws utilized for the reaction types in each element are explained. Agreement between evaluated and experimental data is discussed, and recommendations for improvements are made. In general, evaluations which utilized advanced nuclear model codes, including precompound ... continued below
