Abstract

Abstract The generalized moments of the phonon spectrum ω 2 and ω log, which appear in the Allen-Dynes formula 1 for the critical temperature of superconductors, can be estimated by integrating some functions of the specific heat. As the convergence of this new method is fast, it suffices to know the specific heat up to about one-sixth of the Debye temperature.
