Abstract
Due to its complexity, the fission process still presents nowadays a great interest from both theoretical and experimental point of view. In this context, the FALSTAFF spectrometer aims at providing constraining data that may contribute significantly to an improved description of the fission process. Based on time-of-flight (ToF) and residual energy technique, the one-arm configuration of the FALSTAFF setup will bring a new and interesting piece of information covering incident neutron energies ranging from 500 keV to 20 MeV. It will measure fission-fragment velocities and energies in order to study the evolution of the post-neutron evaporation fragment mass distribution of 235U according to the excitation energy of the compound nucleus and for some available n-chance fission channels. The role of the shell effects and the correlation between fragment mean kinetic energies and masses will be investigated as a function of the incident neutron energy. In addition to improve our fundamental knowledge on the fission process, such data are requested for model developments, especially models devoted to nuclear data evaluations.
