“…The boson peak in the low-frequency Raman spectrum is a handy marker of the glassy phase of substances [9]. The low-frequency Raman spectra of the sample, obtained during cooling of the melt ''M2'' at a cooling rate of 5 1C/min, are shown in Fig.…”

The present contribution reviews recent investigations of the Raman coupling coefficient of the boson peak. Features of the Raman coupling coefficient are in favour of a simple phenomenological model of boson peak vibrations, in which only one type of vibrational excitations exists at one frequency. The vibrations of the boson peak share properties of both localized and diffusively extended excitations.

“…Jackle [14][15][16] has found an explicit relation between the QES scattering intensity and the sound attenuation predicting that the QES intensity vs temperature should have the same behaviour of the acoustic attenuation. Recently Caponi et al [17] have reported convincing results on v-SiO 2 demonstrating that the QES intensity and the -relaxation are strictly connected.…”
