A new evaluation of the neutron data standards

Evaluations are being done for the H(n, n), Li-6(n, t), B-10(n, alpha gamma), B-10(n, alpha), C(n, n), Au(n,gamma), U-235(n, f) and U-238(n, f) standard cross sections. Evaluations are also being done for data that are not traditional standards including: the Au(n,gamma) cross section at energies below where it is considered a standard; reference cross sections for prompt gamma-ray production in fast neutron-induced reactions; reference cross sections for very high energy fission cross sections; the U-235 thermal neutron fission spectrum and the Cf-252 spontaneous fission neutron spectrum and the thermal constants.
