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 transit ion of the liquid-gas type. The mixed phase region of the phase diagram, wh ere the gas of nuclear fragments coexists with the infinite liquid condensa te, is unambiguously identified. The peculiar thermodynamic properties of t he model near the boundary between the mixed phase and the pure gaseous pha se are studied. The results for the caloric curve and specific heat are pre sented and a physical picture of the nuclear liquid-gas phase transition is clarified. (C) 2001 Published by Elsevier Science B.V.
