Interatomic potentials for krypton and xenon

摘要

Accurate potentials for ground state kryptonhyphen;krypton and xenonhyphen;xenon interactions are derived using a wide range of experimental evidence including second virial coefficients, gas transport properties, solid state data, known longhyphen;range interactions, spectroscopic information on dimers, and new measurements of differential scattering cross sections. In calculating solidhyphen;state properties account is taken of longhyphen;range manyhyphen;body interactions. The use of the potentials permits a critical intercomparison of various kinds of experimental data. A ``corresponding states'' comparison of the shapes of the potentials for different inert gas pairs is given. It is concluded that contributions of overlaphyphen;dependent manyhyphen;body interactions to condensedhyphen;phase properties of argon, krypton, and xenon are very small.
