Texas A and M University (Texas A and M) in collaboration with Oak Ridge National Laboratory and the Japan Atomic Energy Research Institute, have been actively studying the delayed neutron emission characteristics of the higher actinide isotopes for several years. Recently, a proton recoil detector system was designed, built, and characterized for use in measuring delayed neutron energy spectra following neutron-induced fission. The system has been used to measure aggregate delayed neutron energy spectra from neutron-induced fission of {sup 235}U and {sup 237}Np. These spectra have also been compared to that calculated using individual precursor P{sub n} values, yields, and spectra from the ENDF/B-VI file.
