Isospin effects of critical behavior in lattice gas model

Isopin effects of the critical phenomena were studied via Xe isotopes in th e frame of the lattice gas model. All the critical temperatures for four Xe isotopes are close to 5.5 MeV at the same freeze-out density of about 0.39 rho(0). The critical values of power law parameter of mass distribution, m ean multiplicity of intermediate mass fragments, information entropy and Ca mpi's second moment show minor dependence on the isospin at the critical po int.
