Abstract :
A least squares analysis of fission neutron standard fields has been performed using the latest measurements and dosimetry cross sections for activation foils, fission chambers, and helium accumulation monitors. Discrepant nuclear data are identified and adjusted spectra for the 235U thermal fission field is presented. Comments are made on the consistency of the nuclear data for the 252Cf spontaneous fission neutron environment
