Integral measurements to test neutron scattering and gamma-ray production cross sections for Be, C, N, H/sub 2/O, and Fe. Final report, Aug 1971--May 1975. [2 to 20 MeV]

Technical Report ·
OSTI ID:7346727
Incident-neutron-energy-dependent measurements of scattered neutrons and secondary gamma rays for small samples of Be, C, N, H/sup 2/O, and Fe have been performed at four scattering angles (30, 55, 90 and 125 degrees). The pulsed-white-neutron source, time-of-flight (TOF) method, and NE-213 detector with pulse-shape discrimination, three-parameter data acquisition with an on-line computer and spectrum unfolding were used to measure incident-neutron-energy-dependent count rates and energy spectra of scattered neutrons and secondary gamma rays for incident neutron energies from 2 to 20 MeV. The measurements provide high sensitivity tests for integral and differential neutron scattering and gamma-ray production cross sections when compared with appropriate transport calculations. Differences between measurements and calculations should be interpretable in terms of specific cross-section deficiencies at well-defined incident-neutron energies from 2 to 20 MeV. The source spectrum of neutrons incident on the samples was measured by TOF using the NE-213 detector. (auth)
