Precision Neutron Total Cross-Sectional Measurements for Natural Carbon at Reactor Neutron-Filtered Beams
Author: O. Gritzay

ISBN:
Category : Carbon
Languages : en
Pages : 7
Book Description
An experimental investigation of the total neutron cross section for natural carbon was made at Kyiv Research Reactor using neutron-filtered beams with energies 24, 59, and 148 keV. The intense neutron beams formed by composite neutron filters at reactor horizontal channels )had fluxes of about 106 to 107 neutron/cm2 s at the fixed neutron energies, which enabled us to measure the neutron cross sections with accuracy better than 1 %. Transmission method was used in these measurements. The results of the measurements are presented together with the analysis of the known previous experimental data and the evaluated nuclear data from ENDF libraries. Sample thickness dependence of the observed neutron cross section, measured at the 148-keV filter, has been detected which hypothetically may be connected with existence of a very strong resonance in the 13C neutron cross section in the energy range 119 to 157 keV.

ISBN: 0323146376

Languages : en
Pages : 549
Book Description
Experimental Neutron Resonance Spectroscopy deals with the experimental technique of neutron resonance spectroscopy. Pulsed accelerator time-of-flight spectrometers and gamma rays from neutron capture in resonances are discussed. Total neutron cross section measurements are presented, along with neutron scattering and capture cross-section measurements and measurements on fissile nuclides. This book is comprised of five chapters and begins with an introduction to pulsed accelerator time-of-flight spectrometers with moderated continued neutron spectra, together with the pulsed Van De Graaff. Experimental techniques used for neutron cross section measurements, including detectors and data acquisition equipment, are then outlined. Scattering measurements and capture measurements as well as gamma-ray spectra from the capture of neutrons in resonances are considered. The final chapter focuses on the detailed and varied experiments that have been performed on the complicated fission process, together with the parameters of the resonances of the fissile nuclides. This monograph will be a useful resource for spectroscopists and physicists.

Author: Said F. Mughabghab
Publisher: Elsevier
ISBN: 044463780X
Category : Science
Languages : en
Pages : 698
Book Description
Atlas of Neutron Resonances: Resonance Properties and Thermal Cross Sections Z=61-102, Sixth Edition, contains an extensive list of detailed individual neutron resonance parameters for Z=61-102, thermal cross sections, capture and fission resonance integrals, average resonance parameters, and a short survey of the physics of thermal and resonance neutrons. The long introduction contains: nuclear physics formulas aimed at neutron physicists; topics of special interest such as valence neutron capture, nuclear level density parameters, and s-, p-, and d-wave neutron strength functions; and various comparisons of measured quantities with the predictions of nuclear models, such as the optical model neutron-induced fission. As in the last edition, additional features have been added to appeal to a wider spectrum of users. These include: spin-dependent scattering lengths that are of interest to solid-state physicists, nuclear physicists and neutron evaluators; calculated and measured Maxwellian average 5-keV and 30-keV capture cross sections of importance to astrophysicists involved in nucleosynthesis modeling; s-, p-, and d- wave average radiative widths; nuclear level density parameters; and average fission widths derived from average fission cross sections. Provides a comparison of average resonance parameters with optical model calculations and with the generalized Landau-Fermi model Presents scattering radii for various partial waves from the analysis of total neutron cross sections in the keV to MeV energy region Includes a brief review of sub-threshold fission Features consistent treatment of average neutron parameters with values from the resolved resonance region
