Abstract

The electron-phonon coupling for La2CuO4-type superconductors is calculated in frameworks of rigid-muffin-tin approximation by two way: first, in spherical approximation of Gaspari-Gyorffy and, second, taking into account the proper local symmetry. In the second case electron-phonon coupling is a few times stronger than in the first one. We conclude that low local symmetry, especially on O1 sites is to a great extent responsible for the strong electron-phonon coupling in perovskite compounds.
