Abstract
The frequency spectra of anomalous very-low-energy excitations (0-0.3 ) in glasses have been measured by inelastic light scattering for a variety of compositions and temperatures. Possible sources for these spectra include configurational degrees of freedom associated with the low-temperature tunneling states.
