摘要：

By means of inelastic cold neutron scattering the density of vibrational states (DVS) has been determined for a series of vitreous materials: SOz, As2& and metallic glass Mg To Znso. In the low-energy range of the spectrum (E - (2 i 10) meV) for these materials DVS reveals a universal, but non-Debye form. The data obtained are compared to different models. A comparison with the Raman scattering data provides the spectral dependence for the coupling of the light to the vibrational excitations. © 1990 The Japan Society of Applied Physics.
