Description
The phonon structure in optical data can be inverted to obtain the transport electron-phonon spectral density α2 Ftr(ω). For more general electron-boson exchange models we test the accuracy of using Allen's approximate relationship between spectral density and optical scattering rate instead of complete Eliashberg equation results. Both, s-wave and d-wave superconducting gap symmetries are considered. (Abstract Copyright [2006], Wiley Periodicals, Inc.)
