Abstract
The authors have evaluated the coefficients of the first nonanalytic logarithmic term in the density expansion for the transport properties of a gas of hard spheres, which is due to long-range dynamical correlations between molecules. Their results resolve present uncertainties about the magnitude of the effect, appear to be consistent with available information from molecular-dynamics calculations, and satisfy bounds for the logarithmic contribution deduced from experimental viscosity data for real gases.Keywords
