Analytical equations of state for boson and fermion hard-sphere fluids ranging from very low to very high densities are constructed. Such equations of state serve as a zero-order (reference) state upon which to build so-called quantum-thermodynamic-perturbation corrections in describing real but sim

β¦ Synopsis
The influence of a "amtinuous" distribution of particle sizes on the equation of state of disperskma ofhard-discs zmd hard-spheres is discussed-The van der Waals one-fluid approlcimation gives simple expressions for the &ange in p_essure with degxe of ~oiydispersity. For hardqheres at low volume :raction, good agreement is obtained with the exact Percus-Yevick result.

## Abstract New molecular simulation data are reported for the compressibility factors of hard spheres covering the isotropic liquid, metastable fluid and solid ranges of density. These data provide a comprehensive set of values for the development of hardβsphere equations of state. In particular,
