dc.description.abstractEn | A direct and complete measurement of isotopic fission-fragment yields of U239 has been performed for the first time. The U239 fissioning system was produced with an average excitation energy of 8.3 MeV in one-neutron transfer reactions between a U238 beam and a Be9 target at Coulomb barrier energies. The fission fragments were detected and isotopically identified using the VAMOS++ spectrometer at the GANIL facility. The measurement allows us to directly evaluate the fission models at excitation energies of fast neutrons, which are relevant for next-generation nuclear reactors. The present data, in agreement with model calculations, do not support the recently reported anomaly in the fission-fragment yields of U239, and they confirm the persistence of spherical shell effects in the Sn region at excitation energies exceeding the fission barrier by a few mega-electron volts. | |
