landscape of Fig. 6 in the asymmetry direction $\alpha$ for large elongations ($c \approx 2.0$). However one should not forget that the fragment mass distribution is decided all along the fission path and not only in the immediate neighborhood of the exit point [@MN70] - [@NPPW79]. As the asymmetric valley is around $1$ MeV deeper than the symmetric fission path in the vicinity of $c \approx 1.8 - 1.9$ where $\alpha \approx \pm 0.035$, the predominant part of the trajectories finally ends up in this asymmetric channel.\

FIG. 6. Same as Fig. 5 but with inclusion of quantal effects.\

FIG. 7. Fission-fragment distribution as function of the asymmetry parameter $\alpha$ (left) and of the fragment mass (right) when quantal effects are omitted.\

FIG. 8. Same as Fig. 7 but with inclusion of quantal effects.\
It is interesting to notice that the average fission time is increased from 8.0 $10^{-17}$ sec to 16.2 $10^{-17}$ sec when going from the LDM picture to the one with shell and pairing corrections.\

FIG. 9. Same as Fig. 6 with a typical asymmetric fission trajectory. In the LDM landscape the symmetric fission barrier at $L = 60$ MeV is of the order of $0.7$ MeV.
