Abstract

If electrons in a metal are heated to a temperature Te greater than the lattice temperature TL, the electron-phonon interaction causes temperature relaxation dTe/dt=γT(TL-Te) which is rapid for TL>θD. A formula γT=3ħλ〈ω2〉/πkBTe is derived, where λ〈ω2〉=η/M is an important parameter in the theory of superconductivity. Quantitative agreement with recent experiments is good.
