Accurate Resistivity and Thermoelectric-Power Calculations for Liquid Na and Liquid K

Calculations for the resistivity of pure liquid Na and K have been performed using the experimental structure factors of Greenfield, Wellendorf, and Wiser and the Shaw optimum model potential with the many-electron effects included via the Toigo and Woodruff dielectric function. We find good agreement with experiment for the resistivity and the temperature dependence of the resistivity. The thermoelectric-power results are somewhat less satisfactory. Exchange and correlation effects are seen to play an even larger role than here-tofore estimated.
