Transfer-induced fission in inverse kinematics: Impact on experimental and evaluated nuclear data bases

Topical collection : Perspectives on Nuclear Dta for the Next Decade; Expérience GANIL/VAMOSInternational audienceInverse kinematics is a new tool to study nuclear fission. Its main advantage is the possibility tomeasure with an unmatched resolution the atomic number of fission fragments, leading to new observablesin the properties of fission-fragment distributions. In addition to the resolution improvement, the studyof fission based on nuclear collisions in inverse kinematics beneficiates from a larger view with respect tothe neutron-induced fission, as in a single experiment the number of fissioning systems and the excitationenergy range are widden. With the use of spectrometers, mass and kinetic-energy distributions may now beinvestigated as a function of the proton and neutron number sharing. The production of fissioning nucleiin transfer reactions allows studying the isotopic yields of fission fragments as a function of the excitationenergy. The higher excitation energy resulting in the fusion reaction leading to the compound nucleus250Cf at an excitation energy of 45MeV is also presented. With the use of inverse kinematics, the chargepolarisation of fragments at scission is now revealed with high precision, and it is shown that it cannotbe neglected, even at higher excitation energies. In addition, the kinematical properties of the fragmentsinform on the deformation configuration at scissio
