Description
This paper reports on neutron capture cross sections for the 197Au(n,γ)198Au reaction that have been determined at neutron energies of 23 and 967 keV. These are the median energies of the two photoneutron sources, Sb-Be and Na-Be, applied in this study. Reaction rates were determined by gamma counting of the 198Au activity using a pair of cylindrical NaI(Tl) detectors. The detection efficiency of the detectors was determined using 4π beta-gamma coincidence counting techniques. The neutron emission rates of the photoneutron sources were determined by indirect comparison with the U.S. National Bureau of Standards NBS-I neutron standard source using the University of Michigan manganese bath. The values obtained for the 197Au(n,γ)198Au cross section are 617.8 ± 11.1 mb and 99.7 ± 2.8 mb at 23 and 967 keV, respectively
