Résumé en anglais

Inverse kinematics is a new tool to study nuclear fission. Its main advantage isthe possibility to measure with an unmatched resolution the atomic number of fissionfragments, leading to new observables in the properties of fission-fragmentdistributions. In addition to the resolution improvement, the study of fission based onnuclear collisions in inverse kinematics beneficiates from a larger view with respect tothe neutron-induced fission, as in a single experiment the number of fissioningsystems and the excitation energy range are widden. With the use of spectrometers,mass and kinetic-energy distributions may now be investigated as a function of theproton and neutron number sharing. The production of fissioning nuclei in transferreactions allows studying the isotopic yields of fission fragments as a function of theexcitation energy. With the access of kinematics properties, the charge polarisation offragments at scission is now revealed with high precision, and it is shown that itcannot be neglected, even at higher excitation energies. Results on fissioning systems238U, 239Np, 240Pu, 244Cm, obtained in transfer reactions are presented, together withthe fusion reaction leading to the compound nucleus 250Cf at an excitation energy of45MeV.< Réduire
