✦ Synopsis
The specific heat from 3K to 15K and the Raman spectra were measured on the As2S3 glass. The specific heat data were fitted using two different models of the vibrational state density, i.e. the phonon-fracton model and the model of lognormal distribution of frequencies. We have shown that the excess vibrational state density which governs the specific heat behaviour gives only a little contribution to the intensity of Raman scattering in the boson peak region.
