Abstract

We have analyzed the ²³⁷Np/²³⁸U fission-rate ratio outside an iron sphere in which a ²⁵²Cf source is placed at the center, measured at NIST, and the leakage spectrum from a similar assembly, measured at NRI (near Prague). The experimental results were compared with the corresponding calculations, respectively based on the ENDF/B-IV, -V and -VI libraries. We found indeed that the newer the library, the better the agreement between experiment and calculation. Yet, even for ENDF/B-VI, the calculated values still differ from the experimental ones by more than the reported standard deviations of the latter.
