Abstract
We show that the superconducting energy gap can be directly observed in phonon spectra, as predicted by recent theories. In addition, since each phonon probes the gap on only a small part of the Fermi surface, the gap anisotropy can be studied in detail. Our neutron scattering investigation of the anisotropic conventional superconductor YNiBC demonstrates this new application of phonon spectroscopy.
