To the question on electron-electron scattering in metals

Temperature dependence of the scattering rate in copper and aluminium has been investigated by the radio frequency size effect with the aim of extracting the contribution of electron-electron collisions. The scattering rate is varied by the cubic law on the wide temperature range (1.2–10°K), which is due to the electron-phonon interaction. On the basis of modern representations on the electron-electron interactions, the absence of the quadratic term in the probability of scattering of charge carriers in these metals, close to the transition ones, is discussed.
