PROTON EMISSION IN REACTION OF 14.6-MEV NEUTRONS WITH NATURAL IRON

The energy spectra and angular distributions of proton emission in a r eaction of Fe-nat(n,xp) at a neutron energy of 14.6 MeV are measured b y the University of Science and Technology of China multitelescope sys tem. The double-differential cross sections of 16 reaction angles from 25 to 164.5 deg are obtained in this measurement. The statistical err ors are reduced largely because of the thick target used. The angular distributions show a slightly energy-dependent forward-backward asymme try. The angle-integrated proton spectrum is compared with theoretical calculations and other results. The fetal proton-emission cross secti on is in fair agreement with the prediction and evaluation.
