Statistical multifragmentation of nuclei (II). Application of the model to finite nuclei disassembly

The fragmentation of a hot nuclear system is studied in a statistical model. The partitions of the system are calculated by means of a Monte Carlo technique. The resulting mass spectra, multiplicity distributions, average values of temperature, entropy, heat capacity and break-up density are presented and discussed. It is found that the fragmentation process begins rather suddenly at a crack temperature T ^∗≃5-6 MeV. The occurrence at a higher temperature of a transition to a gaseous-like phase in finite systems is investigated and compared with infinite-matter calculations.
