The selfβconsistent treatment of electron correlations at, metallic densities, recently given by Vashishta and Singwi, is applied to pseudopotential calculations of electrical resistivity and thermoelectric power of alkali metals. For the liquid structure factor, recent accurate experimental data of Greenfield et al., have been used in case of Na and K, and the hard sphere structure factors in case of Rb and Cs. The pseudopotential used is a local potential of Ashcroft type, with its parameters fixed to give good agreement with phonon dispersion data. Energy dependence of the pseudopotential form factor is deduced from thermoelectric power data. Calculations have also been done with Shaw's nonβlocal pseudopotential for the case of Na and K. For Na, results of calculations of resistivity using three other different screening functions of Hubbard type are also presented.
