Determination of Differential Elastic and Double-differential Neutron Scattering Cross Sections of Elemental Tungsten at Energies between 7.19 MeV and 14.10 MeV
S Khurana, W Mannhart, D. Schmidt
Differential cross sections of elastic and inelastic neutron scattering on elemental tungsten were determined in the energy range from 7.19 MeV to 14.10 Mev at eight incident energies. The data were derived by comparing the net time-of-flight spectra with calculated spectra using a realistic Monte Carlo simulation. The time-of-flight measurement was accompanied by extensive and careful calibrations. The tungsten cross sections were normalized to hydrogen scattering. The disturbing breakup scattering fraction of the non-monoenergetic DD neutron source can be subtracted after having also been calculated by a Monte Carlo simulation.
