The resistivity versus temperature at constant volume of liquid Na, K and Rb

Abstract

The temperature dependence of the electrical resistivity at constant volume was studied to provide more accurate data for comparing Ziman's theory with experiment. Our results were obtained with greater precision over a larger temperature interval than Endo reported. No anomaly in the ρ(T) curves were found for sodium, potassium, or rubidium as was reported for lithium. The definite linear nature of the temperature dependence should make x-ray measurements of I(K) useful in testing the Born approximation.
