Abstract

The 233U fission and capture cross sections were measured using a nuclear-device neutron source and time-­of-flight techniques. Cross section data are presented from 20 to 106 eV for fission and from 20 to 63 eV for fission + capture. The resonance region (20 eV to 63 eV) was fitted with both a single level function consisting of a sum of Breit-Wigner levels and the Reich and Moore multilevel function based on R matrix theory. The resulting resonance parameters are listed and discussed. In order to establish the validity of the resonance parameters derived from the multilevel fit, a study is presented of the cross section derived from two and three hypothetical resonances under various conditions and of the cross sections obtained from randomly generated resonances.
