The present project can be regarded as an attempt to establish the link between different theories for multifragmentation processes, namely percolation theory that has been proposed by several authors as a possible explanation for nuclear fragmentation, lattice gas theory and classical molecular dynamics. The main objectives of the project can be summarized in the following points:
i) To find an explanation to the existence of the scaling property in t size distribution of the fragments within the framework of molecular dynamics, a property that is well established both in percolation and lattice gas theories. ii) To establish a mapping between the thermodynamic phase diagram and the percolation diagram by characterizing the different regions and critical points. iii) To analyse the geometry and size distribution of the fragments as a func- tion of the range of the interaction. The Coulomb long-range interaction will be considered as a special and very interesting case.
