Fission fragments anisotropy in fast-neutron-induced fission of 235U was measured at neutron energies ranging from 0.3 to 1.4 MeV at intervals of 0.1, 1.6, 1.8, and 2.2 MeV. In the present study, the pairing energy gap (2Δ0) for the highly deformed transition state of the nucleus 236U was found to be 2.0 ± 0.06 MeV.
