Abstract
The electrical resistivity of potassium has been measured with high accuracy between 4.2 and 1.1 K. At temperatures above 2 K the dominant term is of the form , with K, which is due to electron-phonon scattering under phonon-drag conditions. At temperatures below 2 K a weak dependence of the form is dominant, where is between 1 and 2. Tentatively one could ascribe this term to electron-electron scattering.
