Least squares analysis of fission neutron standard fields

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 /sup 235/U thermal fission field is presented. Comments are made on the consistency of the nuclear data for the /sup 252/Cf spontaneous fission neutron environment.
