    "abstract": "We perform a study of the fragmentation path of excited nuclear sources,\nwithin the framework of a stochastic mean-field approach. We consider the\nreaction $^{129}$Xe + $^{119}$Sn at two beam energies: 32 and 50 MeV/A, for\ncentral collisions. It is observed that, after the compression phase the system\nexpands towards a dilute configuration from which it may recontract or evolve\ninto a bubble-like structure. Then fragments are formed through the development\nof volume and/or surface instabilities. The two possibilities co-exist at 32\nMeV/A, leading to quite different fragment partitions, while at 50 MeV/A the\nhollow configuration is observed in all events. Large variances are recovered\nin a way fully consistent with the presence of spinodal decomposition remnants.\nKinematical properties of fragments are discussed and suggested as observables\nvery sensitive to the dominant fragment production mechanism. A larger radial\ncollective flow is observed at 50 MeV/A, in agreement with experiments.",
