ProjectESTUDIOS DE DESINTEGRACIONES BETA Y DE REACCIONES PARA LA ESTRUCTURA NUCLEAR, ASTROFISICA Y APLICACIONES (MINECO-FPA2014-52823-C2-2-P)
Since its start in 2001 the n_TOF collaboration developed a measurement program on fission, in view of advanced fuels in new generation reactors. A special effort was made on measurement of cross sections of actinides, exploiting the peculiarity of the n_TOF neutron beam which spans a huge energy domain, from the thermal region up to GeV. Moreover fission fragment angular distributions have also been measured. An overview of the cross section results achieved with different detectors is presented, including a discussion of the 237Np case where discrepancies showed up between different detector systems. The results on the anisotropy of the fission fragments and its implication on the mechanism of neutron absorption, and in applications, are also shown.
