thermal cross-sections and the resonance integrals with the Mughabghab
recommendations and the k 0 database. This analysis is intended to complement
other selection criteria such as format correctness, completeness, internal
consistency of other parameters and availability of covariance information.
Problem areas exist that need to be resolved:
— 50 Cr: The discrepancy between the Mughabghab recommendation and
resonance parameter data in the files needs to be resolved.
— 55 Mn: The discrepancy between the Mughabghab recommendation and
resonance parameter data in the files needs to be resolved.
— 58 Fe: The Q 0 value from the k 0 database suggests preference for JENDL-
3.3 as the source data; the resonance integral should be reassessed.
— 151 Eu: The thermal capture cross-section is practically the same in all data
sources. Although the resonance integral is less important, differences of
almost a factor of three between measurements deserve further attention.
