N2 - Multifragmentation scenarios, as predicted by antisymmetrized molecular dynamics (AMD) or momentum-dependent stochastic mean-field (BGBD) calculations are compared. Whereas in the BGBD case fragment emission is clearly linked to the spinodal decomposition mechanism (i.e., to mean-field instabilities), in AMD many-body correlations have a stronger impact on the fragmentation dynamics. In fact, the density and momentum fluctuations develop earlier in AMD, suggesting that fragments are formed on shorter time scales in AMD, on about equal footing as light-particle pre-equilibrium emission.
