Abstract: A high-resolution measurement of the neutron-induced fission cross section of 234U and 237Np has been performed at the CERN Neutron Time-of-Flight facility. The cross sections have been determined in a wide energy range from 1 eV to 1 GeV using the evaluated 235U cross section as reference. In these measurements the energy determination for the 234U resonances could be improved, whereas previous discrepancies for the 237Np resonances were confirmed. New cross-section data are provided for high neutron energies that go beyond the limits of prior evaluations, obtaining important differences in the case of 237Np.
