Abstract

The Low-Fidelity Covariance Project has developed a complete set of covariance data estimates for all ENDF/B-VII.0 isotopes. Covariance data are provided for elastic scattering, inelastic scattering, (n,2n) reactions, radiative capture and fission (cross section and nubar) over the energy range front 10(-5) eV to 20 MeV. Various approximations were utilized depending on the mass of the target, the neutron energy, range, and the neutron reaction. The resulting covariance data are not art official part of ENDF/B-VII: but are available for testing in nuclear applications.
