Abstract: The neutron-induced fission cross-section of 245Cm was measured at n_TOF in a wide energy range and with high resolution. The energy dependence, measured for the first time in a single measurement from thermal to 1 MeV neutron energy, has been determined with a 3% accuracy relative to the reference 235U(n,f) cross-section. In order to reduce the uncertainty on the absolute value of the cross-sections, the data have been normalized at thermal energy to recent measurements performed at ILL and BRI. The results are in fair agreement with some previous measurements, in the energy range in which they overlap, and confirm in average the cross section extracted from the ENDF-B/VII.0 database, although sizable differences are observed for some important resonances below 20 eV. A similar behavior is observed relative to JENDL/AC-2008, a reactor-oriented database dedicated to actinides. The new results here reported can be useful for improving the accuracy of databases needed for the design of advanced reactor systems, and may lead to refinements of fission models for actinides.
