Notes:
Requirements for satisfactory calculation of high temperature transport properties are discussed, with special emphasis on the role of the intermolecular potential. The determination of appropriate pair potentials from scattering of high energy neutral beams is described, and potentials obtained from helium, neon, argon, krypton, and xenon, each scattered by its own gas, are tabulated. Similar potentials are given for helium scattered by argon, nitrogen, methane, monofluoromethane, difluoromethane, trifluoromethane, and tetrafluoromethane; neon by argon; argon by hydrogen and nitrogen; atomic hydrogen by helium and hydrogen; and atomic deuterium by deuterium gas. Average potentials derived from suitable combinations of these experimental potentials are given for the like-particle systems of nitrogen, methane, monofluoromethane, difluoromethane, trifluoromethane, and tetrafluoromethane.Results of calculations which use suitable and unsuitable potential functions are shown in tabulated form for the coefficient of viscosity, the coefficient of self-duffusion, and the isotopic reduced thermal diffusion ratio of argon and of nitrogen, and in graphical form for the coefficient of viscosity of xenon.
