High Resolution Measurements of the 234U(n,f) Cross Section in the Neutron Energy Range from 0.5 V up to 100 keV
The 234U(n,f) 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 and another in a 2π detection geometry. A 235U(n,f) cross section measurement was performed in the same experimental conditions, allowing a reliable correction for the 235U(n,f) contribution to the yield. Special attention has been given to the strongest resonance at 5.16 eV and to the fission resonance integral If, for which large discrepancies are reported in the literature.
