Abstract
Although it is recognized that the boson peak is a universal and fundamental feature of glass and liquid dynamics arising from low-frequency vibrational modes which are absent in crystals, the source of these modes is still under investigation. The effects are detected as a “bump” in low temperature specific heat measurements, an excess vibrational density of states in inelastic neutron scattering and the “boson” peak in Raman scattering. It is shown that the magnitude, location, and softening of the Boson peak as it persists into the supercooled liquid state are well accounted for by the interstitialcy model of condensed matter states as the resonance modes of self-interstitials.
