Abstract :
We measured angular and energy distributions of neutrons from an iron target bombarded by 210 MeV protons at angles of 0°, 7.5°, 15°, 30°, 60°, 90° and 110° using the RIKEN Ring Cyclotron. The measured results are compared with the calculations using the MCNPX and NMTC/JAM codes with several physics models. These calculations generally agree with the measurements except at forward angles. We also show the angular distribution and total neutron yield from 0° to 180°, integrated above 5 MeV, to compare with similar experiments in the medium energy region of projectile protons.
