The elastically scattering differential cross sections of 14.7 MeV neutrons on Fe at angles between 3.76° and 7.98° are measured. The associated particle time-of-flight method is used to select 14.7 MeV neutrons
which originated from T (

He reaction at the angle near 40° with respect to a 200 keV deuteron beam. The scattering angles and spectra of neutrons are simultaneously determined with a position-sensitive detecting system.
The corrections for neutron flux attenuation
multiple scattering and finite geometry were performed by Monte Carlo method. The experimental results were compared with the available data from other work.
