Binary diffusion coefficients for the systems He4–He3, He4–D2, He4–H2, He3–D2, He3–H2, and H2–D2 from 273 to 320 K: Tests of several potential functions

Abstract
Diffusion coefficients are reported for the six binary systems which can be formed from the components He4, He3, D2, and H2. The results are used to test the assumption that the potential function for a given system is independent of the isotopic nature of each component.
