The temperature dependence of the electron-scattering rate in Cu has been investigated in the range 2 to 20^∘{}K with magnetic-field-induced surface quantum states. From the temperature dependence we obtain the electron-phonon scattering rate at points on the Cu Fermi surface. Over the limited range of our present explorations we observe a scattering-rate anisotropy of nearly a factor of 6, the highest scattering rate being on the necks.
