The thermophysical properties of pure helium-4, neon, argon, krypton and xenon are calculated using ab initio potentials of kinetic theory over the temperature range from 50 to 5000 K at zero-density, including the second virial coefficient, thermal diffusion coefficient and thermal diffusion factor. Comparing with results obtained by empirical potentials, the results of present work are in better agreement with experimental data and recommended values of REFPROP 8.0.
