Popis: The joint consistency of a series of measured quantities and their calculated counterparts is defined. Ten measurements of average cross-sections or average cross-section ratios in benchmark 252Cf spontaneous fission neutron fields are analyzed. The consistency of calculations based on a pure Maxwellian fission spectrum and ENDF/B-V dosimetry cross-sections, and of the corresponding measured values is being tested. Dosimetry cross-section covariance matrices based on ENDF/B-V, and covariances of the measured values are used in the analysis. Clear evidence of an inconsistency is presented and discussed. Removing one measurement results in a consistent data set.
