Fragment production in a finite size lattice gas model

Abstract : The critical behavior of the fragment production is studied within a Lattice Gas Model in the canonical ensemble. Finite size effects on the liquid-gas phase transition are analyzed by a direct calculation of the partition function, and it is shown that phase coexistence and phase transition are relevant concepts even for system of a few tens of particles. Critical exponents are extracted from the behavior of the fragment production yield as a function of temperature by means of a finite size scaling. the result is that in a finite system well defined critical signal as can be found at supercritical (Kertész line) as well as subcritical densities.
