    "abstract": "An isospin lattice-gas model, which is a spin-1 Ising model, is employed to\ninvestigate the liquid-gas phase transition in asymmetric nuclear matter. We\nconsider nuclear matter as a lattice where each lattice site can be either\nempty or occupied by a proton or a neutron, with a nearest-neighbor interaction\namong the nucleons. With the Bragg-Williams mean field approximation, we\ncalculate various thermodynamic properties of nuclear matter for different\ndensities and different proton-neutron asymmetry parameter $s$. Our model\nexhibits liquid-gas phase transition below a critical temperature $T_c$, and\npredicts a monotonic decreasing of $T_c$ as the magnitude of $s$ is increased.\nThe dependence of the nuclear matter isotherms on the asymmetry parameter $s$\nis discussed.",
