Abstract
An ab initio method for calculating electron-phonon coupling parameter s is presented. The method is an extension of the plane-wave-based lin ear-response method for the calculation of lattice dynamics. Results f or the mass enhancement parameter lambda and the electron-phonon spect ral function alpha(2)F(omega) for Al, Pb, and Li are presented. Compar isons are made to available experimental data.
