FISSION FRAGMENT ANGULAR ANISOTROPIES AND INERTIA PARAMETERS
An analysis of selected fission fragment angular distributions from helium-ion induced fission is made using an exact theoretical expression. Theoretical anisotropies obtained with the transition state model are compared with their corresponding values deduced from the statistical scission model. The nuclear moment of inertia extracted from the model calculations are compared with their est...

متن کاملFission Fragment Angular Distribution measurements of 235U and 238U at CERN n_TOF facility
Neutron-induced fission cross sections of 238U and 235U are used as standards in the fast neutron region up to 200 MeV. A high accuracy of the standards is relevant to experimentally determine other neutron reaction cross sections. Therefore, the detection efficiency should be corrected by using the angular distribution of the fission fragments (FFAD), which are barely known above 20 MeV. In ad...
متن کاملPhotofission of heavy nuclei at energies up to 4 GeV.
Total photofission cross sections for 238U, 235U, 233U, 237Np, 232Th, and natPb have been measured simultaneously, using tagged photons in the energy range Egamma=0.17-3.84 GeV. This was the first experiment performed using the Photon Tagging Facility in Hall B at Jefferson Lab. Our results show that the photofission cross section for 238U relative to that for 237Np is about 80% over the entire...
متن کاملNucleon pair breaking in the thermal neutron induced fission of 233U and 235U
2014 The absence of a systematic even-odd effect in the primary fragment mass distributions, which has been recently observed, is discussed in terms of nucleon pair breaking during the saddle to scission transition. It is concluded that the existing experimental data are compatible with the assumption of a process where at least one nucleon pair is broken. J. Physique 44 (1983) 785-790 JUILLET ...
