“…Multifragmentation is characterized by a simultaneous production of many fragments (defined in this work as elements with charge Z≥5). The excitation energy required for the onset of multifragentation has been derived from comparisons with statistical models [36][37][38], and more recently, by measuring the fragment emission time using model-independent Coulomb chronometry [39]. These studies show that multifragmentation occurs above E * =4 MeV/nucleon, which corresponds to a beam energy of 25 MeV/nucleon for the Xe+Sn central collisions.…”

We present an analysis of multifragmentation events observed in central Xe+Sn reactions at Fermi energies. Performing a comparison between the predictions of the Stochastic Mean Field (SMF) transport model and experimental data, we investigate the impact of the compression-expansion dynamics on the properties of the final reaction products. We show that the amount of radial collective expansion, which characterizes the dynamical stage of the reaction, influences directly the onset of multifragmentation and the kinematic properties of multifragmentation events. For the same set of events we also undertake a shape analysis in momentum space, looking at the degree of stopping reached in the collision, as proposed in recent experimental studies. We show that full stopping is achieved for the most central collisions at Fermi energies. However, considering the same central event selection as in the experimental data, we observe a similar behavior of the stopping power with the beam energy, which can be associated with a change of the fragmentation mechanism, from statistical to prompt fragment emission.

We study multifragmentation within the framework of a quantum molecular dynamics model using different binding energy formulae in the secondary algorithm; namely, the minimum spanning tree approach. A comparison of theoretical results with experimental data over a wide range of energy, mass and impact parameter is also presented. Our detailed analysis shows an insignificant difference of different binding energies when used at finite temperatures on the fragmentation pattern which, on the other hand, becomes significant when used for cold matter.
