A new measurement of the H(n,n)H elastic scattering angular distribution at 14.9 MeV

The relative angular distribution of the scattering of neutrons by protons was measured at En = 14.9 MeV neutron energy for center-of-mass scattering angles ranging from 60° to 180°. Absolute angular distribution values were obtained by normalizing the measured line shape to the accurately known n-p total cross section. Initial assessment indicates a somewhat better agreement of the data with the predictions of Arndt and Nijmegen than with the ENDF/B-VII.0 evaluation
