Abstract

An international effort has produced evaluations of the neutron data standards. Evaluations were obtained for the cross section standards: the H(n,n), ⁶Li(n,t), ¹⁰B(n,ay), ¹⁰B(n,a), nat C(n,n), Au(n,y), 2S5 U(n,f), and 238 U(n,f) reactions. Also in the evaluation process, the 238 U(n,y) and 239 Pu(n,f) nonstandard cross sections were evaluated. Many of these are dosimetry cross sections. Evaluations were also obtained for data that are not traditional standards: Maxwellian spectrum averaged cross section for the Au(n,y) cross section at 30 keV, reference cross sections for prompt y-ray production in fast neutron-induced reactions, reference cross sections for very high-energy fission cross sections, the 235 Cf spontaneous fission neutron spectrum and the 235 U thermal fission neutron spectrum, and the thermal constants. The data and covariances were obtained directly from this evaluation procedure as is required by the dosimetry community.
