On the basis of morphological thermodynamics we develop an exactly solvable version of statistical mutifragmentation model for the nuclear liquid-gas phase transition. It is shown that the hard-core repulsion between spherical nuclei…
The isobaric caloric curve is considered in subcritical states region. The energy fluctuations along the caloric curve are determined for small nuclear systems which consist of limited number of nucleons. The temperature dependence of heat…
