    "abstract": "In this paper we continue the investigation of the lattice gas model. The\nmain improvement is that we use two strengths for bonds: one between like\nparticles and another between unlike particle to implement the\nisospin-dependence of nuclear force. The main effect is the elimination of\nunphysical clusters, like the dineutron or diproton. It is therefore a better\ndescription of nuclear system. Equation of state in mean field theory is\nobtained for nuclear matter as well as for $N\\ne Z$ systems. Through numerical\nand analytical calculation we show that the new model maintains all the\nimportant features of the older model. We study the effect of the Coulomb\ninteraction on multifragmentation of a compound system of A=86, Z=40 and also\nfor A=197, Z=79. For the first case the Coulomb interaction has small effect.\nFor the latter case the effect is much more pronounced but typical signatures\nof the lattice gas model such as a minimum (maximum) in the value of $\\tau$\n($S_2$) are still obtained but at a much lower temperature.",
