Fusion-fission dynamics is investigated with a special emphasis on fusion
reactions at low energy for which shell effects and pairing correlations can
play a crucial role leading in particular to multi-modal fission. To follow the
dynamical evolution of an excited and rotating nucleus we solve a 2-dimensional
Langevin equation taking explicitly light-particle evaporation into account.
The confrontation theory-experiment is demonstrated to give interesting
information on the model presented, its qualities as well as its shortcomings.Comment: 19 pages, latex, 24 eps-figure
