Calculated values of the second dielectric and refractivity virial coefficients of helium, neon, and argon.

Description

Values of second dielectric and refractivity virial coefficients computed, with rigorous accounting for quantum effects, from state-of-the-art pair potentials and interaction polarizabilities. Values given at 1 K intervals (finer intervals below 10 K) for helium (both mass 3 and 4 isotopes), neon (both mass 20 and 22 isotopes), and argon (mass 40 isotope). Upper temperature limit is 2000 K in all cases. Lower temperature limit is 0.5 K for helium, 4 K for neon, 50 K for argon. These files are Supplemental information to: G. Garberoglio and A.H. Harvey, "Path-integral Calculation of the Second Dielectric and Refractivity Virial Coefficients of Helium, Neon, and Argon," published in J. Res. NIST , volume 125, article 125022 (2020) [https://doi.org/10.6028/jres.125.022], which describes how the values were calculated.
