Direct determination of the intermolecular potentials for Ne-Ar, Ne-Kr and Ne-Xe

An inversion procedure has been used to obtain, from the extended principle of corresponding states, the intermolecular potential energy functions for Ne-Ar, Ne-Kr, and Ne-Xe over a range of reduced temperature extending from 0.3 to 100. These directly determined potentials are in good agreement with the HFD-B potentials proposed by Barrow et al.
