Abstract
Phase separation of a binary mixture caused by repulsive forces is studied for a binary soft-core mixture with non-additive core-sizes φij(r) = ε(σij/r) n, i, j = A or B, σ AB = (σ AA + σ BB) (1+Ɗ)/2. The system is simulated by a Monte Carlo method with use of the fine-grained lattice model which is made by successive binary-division of the unit cell. The result for case that different species of atoms have the same core size is presented. The critical solution curve on the P-T plane is determined.
