Isotopic Distributions of Fission Fragments from Transfer-induced Fission

Abstract

Expérience GANIL/VAMOS/EXOGAMInternational audienceFissioning systems from U to Cm as well as 250Cf were produced by 238U+12C transfer and fusion reactions. The detection of the target-like transfer partner made the characterization of the fissioning systems in (Z,A) and excitation energy possible. The isotopic identification of the fission fragments was achieved by using the VAMOS spectrometer combined to with reactions in inverse kinematics. Results regarding the populated transfer channels and excitation of the target-like transfer partner are presented, as well as the 240Pu fission probability. Isotopic yields of the fission-fragments for 240,241Pu and 250Cf, having excitation energies of about 10 and 45 MeV, respectively, are discussed
