Capture Cross-Sections of Structural Materials Measured with the Harwell Large Liquid Scintillator

摘要

A preliminary analysis of these measurements has been published in the Proceedings of the Specialist's Meeting on Neutron Data of Structural Materials for Fast Reactors (Pergamen Press, 1979). Since then the results have been subject to considerable revision, and additional measurements have been included in the analysis. Improvements have also been made in the determination of the detector efficiency for capture gamma-rays and its sensitivity to scattered neutrons. Final values for the parameters of the principal resonances observed in natural iron in the energy range 200 eV to 40 keV are presented.
