Nuclear fission dynamic is investigated using spallation reactions induced by protons on 208Pb. This reaction allows to produce fissioning systems with low angular momentum, small deformations, and high excitation energies that enhance the dissipative effects in fission. Kinematically complete measurements of fission fragments and light-charged particles emitted in coincidence were performed by the use of the SOFIA setup combined with the inverse kinematics technique, allowing for the first time a full identification in atomic and mass number of the two fission fragments. These measurements permit to define new fission observables for the investigation of temperature and deformation dependencies of the dissipation parameter. In addition, these new measurements are also interesting for technical applications, such as accelerator-driven systems (ADS), radioprotection in space, and shielding at accelerators.
