  A novel method to access the complete identification in atomic number Z and
mass A of fragments produced in low-energy fission of actinides is presented.
This method, based on the use of multi- nucleon transfer and fusion reactions
in inverse kinematics, is applied in this work to reactions between a 238U beam
and a 12C target to produce and induce fission of moderately excited actinides.
The fission fragments are detected and fully identified with the VAMOS
spectrometer of GANIL, allowing the measurement of fragment yields of several
hundreds of isotopes in a range between A ~ 80 and ~ 160, and from Z ~ 30 to ~
64. For the first time, complete isotopic yield distributions of fragments from
well-defined fissioning systems are available. Together with the precise
measurement of the fragment emission angles and velocities, this technique
gives further insight into the nuclear-fission process.
