Statistical multifragmentation in thermodynamic limit

An exact analytical solution of the statistical multifragmentation model is found in thermodynamic limit. The model exhibits a Ist order phase transition of the liquid-gas type. The mixed phase region of the phase diagram, where the gas of nuclear fragments coexists with the infinite liquid condensate, is unambiguously identified. The peculiar thermodynamic properties of the model near the boundary between the mixed phase and the pure gaseous phase are studied. The results for the caloric curve and specific heat are presented and a physical picture of the nuclear liquid-gas phase transition is clarified. (C) 2001 Published by Elsevier Science B.V.
