New Insights Into the Fission Process by the Study of Relativistic Nuclear Collisions

An experimental and theoretical campaign dedicated to a better understanding of the fission process has been started at GSI several years ago. The waste amount of data measured at GSI gave new information on different aspects of the nuclear-fission process, such as nuclear viscosity at small deformation, transient effects, influence of shell effects on mass- and charge-division in fission, pairing correlations. All this lead to a development of a model, which proved successful in describing fragment formation in spallation and fragmentation reactions
