Characteristic parameters of xenon near its liquid-gas critical point

Abstract

The mean crossover functions estimated from the bounded results of the Massive Renormalization scheme applied to the 4d (n) model in three dimensions (d = 3) and scalar order parameter (n = 1) are used to represent the singular behaviors of the isothermal compressibility of xenon along the critical isochore in the homogeneous domain and the vapor-liquid coexisting densities of xenon in the nonhomogenous domain. The validity range and the Ising nature of the crossover description are discussed in terms of a single scale factor whose value can be analytically estimated beyond the Ising-like preasymptotic domain
