Proton emissions from the reaction of neutrons with stainless steel at a 14.6-MeV neutron energy are measured using a multitelescope system. A 1Cr18Ni9Ti (Type 321) stainless steel is used. The double-differential cross sections (DDCS) of 16 reaction angles from 25 to 165 deg are obtained in this measurement. The energy spectra and the angular distributions of proton emissions are obtained from the DDCS. The angular distributions show a slightly energy-dependent forward-backward asymmetry. The total proton emission cross section is 229 ± 16 mb for a proton energy >2 MeV.
