Abstract
Liquid-gas phase transition in asymmetric nuclear matter is investigat ed with an isospin lattice gas model. Nuclear matter is considered as a lattice with each lattice site either empty or occupied by a proton or a neutron, with a nearest-neighbor interaction between the nucleons . The Bragg-Williams mean field approximation is employed to evaluate the thermodynamic potential. Our model exhibits liquid-gas phase trans ition below a critical temperature.
