This book was released on 1990 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Integral Measurements to Test Neutron Scattering and Gamma-Ray Production Cross Sections for Be, C, N, H2O, and Fe by : L Harris (Jr)
Download or read book Integral Measurements to Test Neutron Scattering and Gamma-Ray Production Cross Sections for Be, C, N, H2O, and Fe written by L Harris (Jr) and published by . This book was released on 1975 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

This book was released on 1969 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: A gamma-ray production cross section measurement facility is described in this report. This facility uses a LINAC as a neutron source and a Ge(Li) as the gamma detector. The facility was used to measure the gamma-ray production cross sections of nitrogen and oxygen for incident neutron energies of up to 16 MeV. The results are tabulated, graphed, and compared with other measurements. (Author).

Download or read book Re-measurement of the Neutron-induced Gamma-ray Production Cross Sections for Iron in the Energy Range 850 KeV Less Than Or Equal to E/sub N/ Less Than Or Equal to 20. 0 MeV. [Tables]. written by and published by . This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Values of the gamma-ray production cross sections for neutron interactions with iron as reported by previous investigators have differed by as much as a factor of 1.5 or more at neutron energies greater than about 5 MeV. Because of this discrepancy, the measurements were repeated at ORNL using the ORELA as a pulsed source of neutrons with energies between 850 keV and 20 MeV. The data were obtained using a NaI(Tl) gamma-ray spectrometer oriented at an angle of 125° to the incident neutron beam. The sample was positioned in the beam at a distance of 47.35 meters from the neutron source. The resulting data, presented as differential cross sections (d2sigma/d.cap omega.dE) for gamma rays between 0.7 and 10.5 MeV, show good agreement with some previously published data, but are significantly different from previous ORNL measurements for neutron energies greater than 5 MeV.

Available in PDF, EPUB and Kindle. Book excerpt: Experimental measurements of the differential cross sections for the production of gamma rays in natural silicon and tungsten in the energy range from 5.0 to 11.0 MeV are presented. Theoretical calculations of the production cross sections for silicon, based on statistical theory and the Satchler formalism, with modifications by Moldauer, have been made, and comparisons of these calculations and other nuclear model calculations with experiment are discussed.

Download or read book Cross Section Standards for Neutron-induced Gamma-ray Production in the MeV Energy Range written by and published by . This book was released on 2004 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
