Abstract
We provide evidence for the universal behavior of the exponent characterizing the singularity of the Mayer fugacity series for the pressure of a fluid. As long as the two-body potential is positive but otherwise unrestricted, this exponent appears to be independent of the form of the potential and it is a monotonic, slowly increasing function, φ(D), of the dimensionality D of the system. A limited version of universality has previously been proposed by Poland [J. Stat. Phys. 35, 341 (1984)], restricted to hard, approximately spherical particles. Our results for φ(D) differ somewhat from those of Poland.Keywords
