摘要：

The experimental observation of phonon renormalization in high-T(c) superconductors gives clear evidence for the action of electron-phonon coupling. But in spite of the estimated coupling strength lambda approximately 1 - 3, these effects do not allow for a unique identification of the coupling mechanism. This situation is contrasted with that for the low-T(c) superconductors where tunneling spectroscopy provides a hard proof for electron pairing via phonons.
