Abstract

Measurements have been carried out for 14.6 MeV neutrons incident on natural iron using the associated particle time-of-flight technique. The elastic differential and neutron emission cross sections have been measured in the energy range 4.5--13.5 MeV and laboratory angular range 30\ifmmode^\circ\else\textdegree\fi{}--130\ifmmode^\circ\else\textdegree\fi{}. Monte Carlo simulation has been used for multiple scattering and flux attenuation corrections. A value of 477\ifmmode\pm\else\textpm\fi{}48 mb has been obtained for the neutron emission cross section in the energy range 4.5--13.5 MeV. The present measurements have been compared with previous measurements and model calculations.
