The neon–argon potential revisited

The neon–argon interaction has been reexamined in the light of new data, both theoretical and experimental. Two recent potentials have been analyzed as to their ability to predict both macro- and microscopic properties. Both of these fail to give a complete description of the interaction. A new simple potential is presented which accurately predicts a wide range of properties including high and low energy total cross sections, differential cross section, as well as second virials, viscosity, and diffusion. New combining rules have been tested and are found to be consistent with the new potential.
