Abstract
Molecular dynamics calculations of the shear and bulk viscosity and the self-diffusion constant were made for several states of liquid Na and K along the saturated vapour-pressure curve up to the temperature 1800K. The authors used the effective pair potential between ions developed by Price et al. (1970) with the Ashcroft pseudopotential and the dielectric screening function of Geldart and Vosko (1966). Over the whole temperature range the difference between the values obtained for the transport coefficients and the experimental ones is not more than 30%.
