Book Description
Incident-neutron-energy-dependent measurements of scattered neutrons and secondary gamma rays for small samples of Be, C, N, H2O, 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 online computer and spectrum unfolding were used to measure incident-neutron-energy-dependent, count rates and energy spectra of scattered neutrons (E sub n> 1 MeV) and secondary gamma rays (E sub gamma> 1 MeV) 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. (Author).

Book Description
The continuous energy (white) neutron source at the Los Alamos Meson Physics Facility (LAMPF) is used to measure photon-production cross sections over a wide range of neutron energies. Detector systems have been or are being developed to measure gamma rays in the energy range from hundreds of keV up to several hundreds of MeV. In particular a high resolution Ge detector system is used to detect gamma rays from several hundred keV to over 6 MeV. A 5 crystal BGO detector system is used for measuring gamma-rays from 1 MeV to approximately 20 MeV. A large volume BGO detector with an active shield is used to measure gamma rays in the range from 5 to 40 MeV. We are presently developing a multi-element gamma-ray telescope to measure gamma rays with energies from 50 MeV up to several hundred MeV.

Book Description
Gamma-ray cross section standards for neutron-induced reactions are important in enabling the accurate determination of absolute cross sections from relative measurements of gamma-ray production. In our work we observed a need for improvement in these standards. In particular there are large discrepancies between evaluations of the {sup nat}Fe(n, n1'[gamma]) cross section for the 847-keV gamma ray. We have performed (1) absolute cross section measurements, (2) measurements relative to the {sup nat}Cr(n, n1'[gamma]) 1434-keV gamma ray, and (3) comparisons using measured total and elastic scattering cross sections to refine our knowledge of the Fe cross section and the closely linked inelastic channel cross section for Fe. Calculation of integral tests of the cross section libraries may indicate that adjustment of the angular distributions of the neutron elastic and inelastic scattering may be needed.
