“…The thermal cross sections of the two measurements were consistent. Later, activation measurements in the fast neutron region were made by J. F. Barry et al [5] using the Van de Graaf accelerator, and the same measurement was also reported by D. C. Stupegia et al [6] from Argonne National Laboratory. Both measurements overestimate the neutron capture cross section as shown in Fig.…”

“…Not all γ rays emitted by the target and passing through DANCE will produce a count. The probability a γ ray will interact with the detector and produce a count is the efficiency of the detector: ε n,γ/n,f = Detected counts within the cuts Total number of capture/fission events (5) The single γ-ray efficiency is determined with standard γ-ray sources whose activities are known. It is essential to know the detector response functions for γ-rays with different energies and multiplicities.…”

The 236 U(n, γ) reaction cross section has been measured for the incident neutron energy range from 10 eV to 800 keV using the DANCE γ-ray calorimeter at the Los Alamos Neutron Science Center. The cross section was determined with the ratio method, a novel technique using the 235 U(n, f ) reaction as a reference. The results of the experiment are reported in the resolved and unresolved resonance energy regions. Individual neutron resonance parameters were obtained below 1 keV incident energy using the R-Matrix code sammy. The cross section in the unresolved resonance region is determined with improved experimental uncertainty. It agrees with both ENDF/B-VII.1 and JEFF-3.2 nuclear data libraries. The results above 10 keV agree better with the JEFF-3.2 library.
