A new evaluation of the neutron data standards

Abstract

Evaluations are being done for the H(n,n), ⁶Li(n,t), ¹⁰B(n,αγ), ¹⁰B(n,α), C(n,n), Au(n,γ), ²³⁵U(n,f) and ²³⁸U(n,f) standard cross sections. Evaluations are also being done for data that are not traditional standards including: the Au(n,γ) 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 ²³⁵U thermal neutron fission spectrum and the ²⁵²Cf spontaneous fission neutron spectrum and the thermal constants.
