Critical phenomena of the hard-sphere lattice gas on the simple cubic lattice

We study the critical phenomena of the hard-sphere lattice gas on the simple cubic lattice with nearest neighbour exclusion by the Monte Carlo method. We get the critical exponents β/v = 0.313 (9) and γ/v = 2.37 (2), where β is the critical exponent for the staggered density, γ for the staggered compressibility, and v for the correlation length.
