Abstract

Measurements of the temperature dependence of the electrical resistivity of sodium and potassium give

ρ = ρ_{0} + A T^{n}

, with

n = 2.0 \pm 0.1

below 2.1 K for sodium and below 1.4 K for potassium, where

ρ_{0}

is the residual resistivity. It was found that

A

is sample dependent, varying linearly with

{(\frac{ρ_{d}}{ρ_{0}})}^{2}

, where

ρ_{d}

is the contribution to

ρ_{0}

arising from electron-dislocation scattering.
