  In this work we present our findings performing low frequency Raman
measurements over temperature in a tellurite-tungstate glass sample. The
spectra could be fitted by using only two log-Gaussians, which suggests that
quasi-elastic light scattering is negligible. The positions of the peaks have
the same temperature behavior, being the higher frequency one refered as Boson
Peak in literature. The similar temperature behavior and depolarization ratio
indicates that the peaks may have the same origin, being linked to the
tranversal and longitudinal vibrations of some unit.
