First preliminary results of fragments distribution as a function of the excitation energy for different fissioning systems from U to Cm and 250Cf are presented. A new method based on inverse kinematics to study transferinduced fission of minor actinides was carried out in GANIL in 2008, and again in 2011. In these experiments, a 238U beam at 6.1 AMeV impinged on a carbon target to produce fissioning systems by multi-nucleon transfer reactions, resulting in the first experiments accessing the full identification of a collection of fissioning systems and their corresponding fission fragments distribution. The excitation energy is deduced from the detection of the recoil nucleus in an angular DE-E stripped silicon telescope, and the identification of the fragments is made possible by the VAMOS spectrometer.
