energy surface including shell and pairing corrections. As in the case without particle evaporation, one observes an increase of the fission time when quantal effects are taken into account. Whereas the neutron pre-scission multiplicity is larger in the calculations with microscopic corrections, charged particle multiplicities are smaller. With Fig. 3 we have seen that neutrons can be emitted whatever the nuclear elongation, i.e. all along the fission path, and that their emission probability increases with increasing deformation. A longer fission time should therefore lead to a larger neutron multiplicity. Charged particles are preferentially emitted at large deformations (see again Fig. 3). One has, however, to remember that when charged particle emission is favored a substantial amount of the available excitation energy of the emitting nucleus can already have been carried away through neutron emission. In addition one finds that the gradient of the potential energy for the asymmetric fission path including quantal effects is larger between saddle and scission points than the one of the symmetric valley of the LDM landscape. This suggests that the corresponding time scale for the descent from saddle to scission is smaller in the case when shell and pairing effects are present what again favors
