The Energy Dependence of the Neutron Absorption and Fission Cross Sections of U ranium-235 and Plutonium-239 Below 1 eV and the Wescott g Factors

The energy dependence of some experimentally derived neutron absorption and fission cross sections of ²³⁵U and ²³⁹Pu are compared with the ENDF/B-IV results over the energy range from 0.005 to 1.0 e V. Wescott g factors are presented as calculated from the experimental data. The experimental results published previously were normalized to ENDF/B-III values for σ_f and σ_a.
