Abstract
In the present report numerical results concerning the longitudinal ion viscosities, heat conductivities and thermal diffusion ratios in magnetized D-He and H-C plasmas are presented within Grad`s 21 moment approximation. The results are based on analytical formulae given in ref./1/. Calculations taking full account of the finite mass ratio m{sub +}/m{sub z} between hydrogen (deuterium) and impurity ion mass are compared with those for m{sub +}/m={sub z} < 1. As is to be expected, the largest discrepancies between exact and approximate results (with respect to the mass ratio) arise for D-He plasmas. It turned out that the approximate formula for the impurity ion heat conductivity has to be extended to remove some hitherto existing deficiencies already mentioned. (orig.).
