Recent Experiments on Cf-252 Spectrum-Averaged Neutron Cross Sections

Abstract

Spectrum-averaged cross sections of the reactions V-51(n,p), V-51(n,α), Cu-65(n,2n), Zn-64(n,p), I-127(n,2n) and Hg-199(n,n’) were measured relative to Ni-58(n,p) or In-115(n,n’). The data were compared with other experiments and with calculations. A complete uncertainty covariance matrix was derived for the data. The correlation of the present data with previous experiments is also shown. This information and the data of a few recent other experiments were used to update the evaluation of a complete set of experimental spectrum-averaged cross sections determined in the standard neutron field of Cf-252.
