A direct inversion procedure is used to obtain the pair interaction potentials for He and Ne from the extended law of corresponding states over the temperature range from absolute zero to the onset of ionization. We have used the experimentally reduced viscosity collision integrals obtained from the corresponding states correlation and performed an INVERT to determine the reduced potential energy curve corresponding to the collision integral. This directly determined potential is in excellent agreement with the potential independently obtained from molecular beam scattering measurements. © 1995 by John Wiley & Sons, Inc.
