We formulate a model for the disassembly of a highly excited finite nuclear source into interacting nuclear fragments. Monte Carlo sampling of the exact microcanonical and canonical ensemble provides many-fragment configurations at the effective freeze-out stage. The effect of including the interaction between the fragments is significant and an elaboration of the model that allows for a nucleon vapor suggests the existence of a first-order phase transition.
