Abstract
The 4D Langevin equations are well know to give the reasonable good description of the fusion-fission and fusion-evaporation reaction in middle energy excitation range. The computations have been done for Xe+Al which leads to $^{187}$Pb to be able to study the reactions between 8 and 20 MeV/A collected with the INDRA detector. This case is extremely difficult for the Langevin approach as tests limits of using the transport theories. The first estimations are very promising and allow to discuss the primary and secondary fission. Short discussion of lately published influence of the asymmetric charge distribution in fission fragments will be also presented.
