Approximate analytical structure and thermodynamics for penetrable sphere fluids using effective hard spheres

摘要

A penetrable sphere fluid is modeled using the effective hard sphere fluid and its known structure and thermodynamics. It is observed that the obtained equation of state and the radial distribution function are in fairly good agreement with computer simulation data both at low temperatures and/or low densities.
