Accurate measurement of the standard 235U(n,f) cross section from thermal to 170keV neutron energy
An accurate measurement of the 235U(n,f) cross section from thermal to 170 keV of neutron energy has recently been performed at the n_TOF facility at CERN using 6Li(n,t)4He and 10B(n,_)7Li as references. This measurement has been carried out in order to investigate a possible overestimation of the 235U fission cross section evaluation provided by most recent libraries between 10 and 30 keV. A custom experimental apparatus based on in-beam silicon detectors has been used, and a Monte Carlo simulation in GEANT4 has been employed to characterize the setup and calculate detectors efficiency. The results evidenced the presence of an overestimation in the interval between 9 and 18 keV and the new data may be used to decrease the uncertainty of 235U(n,f) cross section in the keV region.
