| Popis: | The relative cross sections for scattering of neutrons by protons have been measured at ${E}_{n}=10 \mathrm{MeV}$ for center-of-mass neutron scattering angles from $60\ifmmode^\circ\else\textdegree\fi{}$ to 180\ifmmode^\circ\else\textdegree\fi{}. Absolute differential cross section values were obtained by normalizing the angle-integrated relative angular distribution to the $n\ensuremath{-}p$ total cross section. The angular distribution exhibits a backward enhancement consistent with an exchange component of the $n\ensuremath{-}p$ interaction at this energy. The relative shape of the angular distribution is in good agreement with the prediction of the charge-dependent Bonn and Nijmegen potential models and with the Arndt phase-shift analysis. Better agreement is found with the evaluated nuclear data files (ENDF)/B-V than with the ENDF/B-VI evaluation. |
