Findings

Coulomb and isospin interactions significantly affect the phase transition behavior.

The symmetry energy properties vary with temperature and nuclear composition.

Finite size effects alter the characteristics of the liquid-gas phase transition.

Abstract

It has been proposed that multifragmentation can be related to the liquid-gas phase transition of nuclear matter. We study the statistical properties of finite nuclear matter near the phase transition with the help of a Lattice Gas Model (LGM). The original version of LGM with only one type of charge-neutral particles is well known to feature the properties of the liquid-gas phase transition. In this contribution, we address the effect of Coulomb and isospin dependence interaction for the finite nuclei transition, and study the symmetry energy properties of finite temperature systems.
