Spinodal Decomposition of Atomic Nuclei

During the multifragmentation of atomic nuclei it seems that identical (or almost identical) initial conditions are leading to very different partitions of the system in interaction. In such a case it is necessary to develop approaches that are able to describe the observed diversity of the final channels. On the other hand the multifragmentation being characterised by the formation of relatively large fragments, one may think that the mean field plays an important role to organise the system in nuclei. Indeed, the mean field (ie, the long range part of the bare nucleon-nucleon interaction) is at the origin of the cohesion of the clusters. Moreover, it has been shown that extentions of mean-field approaches including a Boltzmann-like collision term were providing excellent descriptions of many aspects of heavy ion reactions around the Fermi energy (see for example ref.[1]and references therein).
