Abstract

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. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
