✦ Synopsis

The statistical mechanics of an explicitly soluble model is investigated where classical particles interact by an attractive, quasitranslation invariant but particle-numberdependent potential. Two phases result, one gaseous, the other consisting of gas and one cluster of condensed matter. In the microcanonical ensemble there is a region of negative specific heat and a transition between the two phases at a certain energy where temperature and density jump. In the canonical ensemble -which is not equivalent to the former in this region -the phase transition manifests itself by a jump in energy and density at the transition temperature.
