Distribution of Light Particles Emitted from Fissioning Nuclei

C. Schmitt, J. Bartel, A. Surowiec, K. Pomorski

The formation of an excited rotating deformed nucleus and its subsequent decay through the fission process, or ending up as an evaporation residue, is studied taking into account particle evaporation. Several nuclei ranging from 126Ba to some super-heavy elements are investigated. Until recently, we have only considered average pre-fission multiplicities, as these were the experimental available data. A newly developed analysis of experimental data can now give access to pre-fission multiplicity distributions. A first comparison between theoretical and experimental particle-multiplicity distributions is given.
