Abstract
Scintillation spectrometer analysis of the gamma-ray spectrum arising from interaction of 3.2-Mev neutrons with chromium shows several gamma rays including a very pronounced 1.43-Mev line. Coincidence observations indicate that there are a negligible number of gamma rays in cascade with the 1.43-Mev line. Thus the residual nucleus is left in the 1.43-Mev state by emission of a neutron which carries off the remaining portion of the energy. The energy distribution of this group of inelastically scattered neutrons as deduced from the coincidence pulse-height distribution of recoil protons in a stilbene detector has a maximum at 1.5 Mev.
