Title: 252Cf anti nu discrepancy and the sulfur discrepancy

Abstract

The cantankerous discrepancy among measured values of anti ..nu.. for /sup 235/Cf appears at last to be nearing a final resolution. A recent review has summarized the progress that has been achieved through revaluation upward by 0.5% of two manganese bath values anti ..nu.. and the performance of a new liquid scintillator measurement. A new manganese bath measurement at INEL is in reasonably good agreement with previous manganese bath values of /sup 235/Cf anti ..nu... It now appears that the manganese bath values could still be systematically low by as much as 0.4% because the BNL-325 thermal absorption cross section for sulfur may be as much as 10% low. There is a bona fide discrepancy between measurements of the sulfur cross section by pile oscillators and the values derived from transmission measurements. The resolution of this discrepancy is a prerequisite to the final resolution of the /sup 235/Cf anti ..nu.. discrepancy. 22 references.
