Abstract
The secondary-beam facility at GSI allows to produce a large variety of exotic nuclei at
relativistic energies. This technique offers a unique oportunity to
investigate systematically fission in inverse kinematics. In the
present experiment, the fission properties of more than 70
different actinides and preactinides were investigated at low
excitation energy. The elemental yields and kinetic energies of the
fission residues present new signatures of shell structure and
pairing correlations.
