Rigorous Proof of a Liquid-Vapor Phase Transition in a Continuum
Particle System 
(21K, ReVTeX)

ABSTRACT.  We consider particles in ${\Bbb R}^d, d \geq 2$, interacting
via  attractive pair and  repulsive four-body potentials  of the Kac
type.  Perturbing about mean field theory, valid when the interaction range
becomes infinite, we prove rigorously the existence of a liquid-gas phase
transition when the interaction range is finite but long compared to the
interparticle spacing.
