Abstract: The neutron-induced fission cross sections of 233U, 234U, 235U, 238U, 232Th, 237Np, 209Bi, natPb have been measured at the n_TOF facility at CERN over 9 orders of magnitude in neutron energy using 235U as a reference. Parallel Plate Avalanche Counters were used to detect both fission fragments in coincidence, thus efficiently discriminating fissions from other reactions. Data benefit from the remarkable energy resolution of the n_TOF facility. They are found in overall good agreement with databases and previous measurements, but some clear discrepancies can be put in evidence. These data are the first full coverage of the high-energy region (up to 1 GeV).
