Abstract

In the Surrogate Method, the measured decay probability of a compound nucleus formed via a direct reaction is used to extract the cross section for a reaction with a different entrance channel that proceeds through the same compound nucleus. An extension of the Surrogate Method, the Surrogate Ratio Method (SRM), uses a ratio of measured decay probabilities to infer an unknown cross section relative to a known one. To test the SRM we compare the direct-reaction-induced fission probability ratio of ²³⁴U(α, α’ f ) to ²³⁶U(α, α’f ) with the ratio of cross sections of ²³³U(n, f ) to ²³⁵U(n, f ). These ratios were found to be in agreement over an equivalent neutron energy range of 0.4–18 MeV.
