Abstract

The ²³⁴U(nf) cross section has been measured in the energy range from 0.5 eV to 100 keV at the GELINA neutron time-of-flight facility of the Institute for Reference Materials and Measurements in Geel using highly enriched ²³⁴U samples. Two independent measurements were performed: one in a low detection geometry (15% of 2π) and another in a 2π detection geometry. A ²³⁵U(nf) cross-section measurement was performed under the same experimental conditions, allowing a reliable correction for the ²³⁵U(nf) contribution to the yield. Special attention has been given to the strongest resonance at 5.16 eVand to the fission resonance integral I^f, for which large discrepancies are reported in the literature.
