PROTON EMISSION CROSS-SECTIONS FOR BOMBARDMENT OF STAINLESS-STEEL BY 14.6-MEV NEUTRONS

Proton emissions from the reaction of neutrons with stainless steel nt a 14.6-MeV neutron energy are measured using a multitelescope system A 1Cr18Ni9Ti (Type 321) stainless steel is used. The double-differenti al cross sections (DDCS) of 16 reaction angles from 25 to 165 deg are obtained in this measurement. The energy spectra and rite angular dist ributions of proton emissions ave obtained from the DDCS. The angular distributions show a slightly energy dependant forward-backward asymme try. The total proton emission cross section is 229 +/- 16 mb for a pr oton energy >2 MeV.
