In order to determine $\Gamma_{\nu}^{\mu \kappa}(E^*,L)$ we use two different prescriptions.

FIG. 3. Emission widths for neutrons, protons and $\alpha$ particles emitted from the system $^{160}$Yb (E$^*$=50 MeV, L=40$\hbar$) as a function of elongation.

In Weisskopf’s evaporation theory [@Wei37] the decay rates are essentially evaluated through the level densities of the mother and the daughter nuclei and the transmission coefficient for emitting the particle from a given point of the nuclear surface into a given direction as explained in ref. [@PBR96]. In practice it is not possible to discuss the values of the emission width for each energy, angular momentum and position of the emission point on the nuclear surface. We therefore use them to determine the probability $\Gamma_{\nu} (E^*,L)$ of emitting a given particle from a given nucleus at given deformation. This simplified procedure calculates a transmission coefficient obtained by an averaging over the different emission directions and over the whole surface of the deformed nucleus. A detailed description of this procedure can be found in ref. [@PBR96]. Also other groups [@SDP91; @AAR96; @Fro98] have dealed with particle emission in connection with fission dynamics but, to our knowledge, none of them has taken nuclear deformation explicitly into account as
