Electron-Phonon Enhancement of Electron-Electron Scattering in Al

The influence of the electron-phonon interaction on electron-electron scattering in simple metals has been described within the framework of Landau Fermi-liquid theory. The predicted electron-electron scattering contribution to the low-temperature resistivity of Al is enhanced by a factor of \ensuremath{\sim}20 by the electron-phonon interaction and is in excellent agreement with recent experiments.
