Abstract
The resistivity of free-hanging K wires cooled in He gas varies anomalously with temperature when the diameter becomes comparable to the mean free path for scattering of electrons by impurities. Wires with display a negative in the vicinity of 1 K. It is suggested that this is the first experimental evidence for an interaction between surface scattering and normal electron-electron scattering as first proposed by Gurzhi. The new data also show that previous explanations of K data of Rowlands et al. are inadequate.
