Measurement of the differential cross section of neutron scattering on deuterium in the neutron energy range from 400 keV to 2.5 MeV

Abstract

The angular distribution of n-d scattering was investigated in the energy range from 400 keV to 2.5 MeV using the recoil detection method, irradiating a proportional counter filled with deuterated gases with monoenergetic neutrons. Several techniques were employed to minimise the contribution of photons to the pulse-height distributions. A dedicated Monte Carlo model was developed to determine the differential cross section that best reproduces the measurements. The results are compared with theoretical calculation and the ENDF/B-VII.1 evaluation.JRC.G.2-Standards for Nuclear Safety, Security and Safeguard
