3D stochastic mean-field simulations of the spinodal fragmentation of dilute nuclei

We study the spinodal decomposition of hot and dilute nuclear systems using a stochastic one-body approach in 3D. The early clusterization process appears dominated by unstable modes with well defined multipolarity and radial structure, which can be related to infinite nuclear matter properties. These instabilities favour primary partitions of the system in nearly equal mass fragments, in association with a lack of small clusters. Finally, we discuss how these features are affected by the final decay of the formed fragments.
