Isotopic resolution of fission fragments from $238U+12C$ transfer and fusion reactions

Recent results from an experiment at GANIL, performed to investigate the main properties of fission‐fragment yields and energy distributions in different fissioning nuclei as a function of the excitation energy, in a neutron‐rich region of actinides, are presented. Transfer reactions in inverse kinematics between a $238U$ beam and a $12C$ target produced different actinides, within a range of excitation energy below 30 MeV. These fissioning nuclei are identified by detecting the target‐like recoil, and their kinetic and excitation energy are determined from the reconstruction of the transfer reaction. The large‐acceptance spectrometer VAMOS was used to identify the mass, atomic number and charge state of the fission fragments in flight. As a result, the characteristics of the fission‐fragment isotopic distributions of a variety of neutron‐rich actinides are observed for the first time over the complete range of fission fragments.
