Quantum corrections to the properties of a dense fluid with non-analytic intermolecular potential function

Abstract

Expressions derived in the previous paper for quantum corrections to the properties of a fluid are applied to the hard-sphere fluid. Numerical results are given for the first- and second-order corrections to the free energy and to the pressure, and for the first-order correction to the radial distribution function. Significant features are the large increase in quantum corrections with increasing density, and the qualitative difference that quantum mechanics makes to the radial distribution function near the hard core.
