Fission of Radioactive Beams and Dissipation in Nuclear Matter*

The use of radioactive beams in inverse kinematics dramatically increased the number of isotopes which can be studied at excitation energies ranging from a few to several hundred MeV. Since this method is not subject to target restrictions, long isotopic and isotonic chains could be investigated, and hence, studies of the evolution of fission fragment charge yields, of total kinetic energies, as well as of the time scale of nuclear fission of highly excited compound nuclei with proton and neutron number of the fissioning nucleus, are possible.
