Abstract
The quantum characteristics of liquid neon at four state points have been studied by means of Monte Carlo simulations involving two effective pair potentials arising from the path-integral formalism, namely the quadratic (QFH) and the Gaussian (GFH) Feynman-Hibbs (FH) potentials. Results include mechanical, thermal and structural properties for the FH and the classical Lennard-Jones models. The procedure to compute thermal quantities has been based on Widom's insertion technique. The data reported in the paper are also compared, where possible, with previous path-integral simulation results and with available experimental information.
