Abstract :
Prompt-fission-neutron spectra for neutron-induced fission reactions on uranium and plutonium isotopes are important for nuclear applications. We have used 6Li-glass scintillation detectors to measure outgoing neutron energies in the range from 10 keV to 1 MeV, where there is currently large uncertainty in nuclear data. To better understand the response of 6Li-glass detectors in this energy range, measurements of well-known spontaneous-fission neutrons from a 252Cf source were done in the neutron-beam flight path. Results were compared with Monte Carlo simulations and they show good agreement. Similar measurements with a 7Li-glass detector were used to assess gamma-ray background yields.
