Damping of one-electron excitations in metals
Al'tshuler B.L., Aronov A.G.
It is shown that the scattering of conduction electrons by static defects in metals, although it in itself does not lead to energy relaxation of the excitations, does have a significant influence on the damping of these excitations due to the interaction between electrons. For a sufficiently low excitation energy its damping is proportional to the energy to the three-halves power, and not the square of the energy, as in the Landau theory of a Fermi fluid, which ignores the finiteness of the electron free path.
