Abstract: | The resistivity, thermoelectric power at the melting points and temperature variation of resistivity of the liquid alkali
metals are studied with local Heine-Abarenkov and the modified Ashcroft pseudopotentials. The parameters of the model potentials
are obtained from a unified study of the static and dynamic properties of the metals. The effect of different dielectric function
and structure factor on the transport properties is discussed. It is shown that the simple modified Ashcroft pseudopotential
reproduces the result fairly well except for Li and Cs. |
