Vapor phase thermal diffusion measurements with considerably less scatter than previous data for equimolar mixtures of 3He and 4He are examined against the most recent interparticulate potential function for helium. Calculations are done for the purely classical case; for the quantal (phase-shift) case using Boltzmann statistics; and for the quantal case with Fermi–Dirac statistics for 3He and Bose–Einstein statistics for 4He. A ‘‘hump’’ appearing in the quantum-statistical curve, which is in disagreement with the experimental results, indicates that at the vapor densities reported here the use of quantum statistics is unnecessary.
