- 論文の詳細を見る
The Brillouin scattering spectra of B.0, glass have been observed as a function oftemperature is a range from 300 K to 630 K over the glass transition temperature T..The Brillouin frequency shifts of both the longitudinal and the transverse modes arealmost independent of temperature below T., and show a gradual decrease with in-creasing temperature above T.. An analysis is proposed using a modified two-statemodel, where a freezing of the two-state system was assumed and a background termin the free energy was taken into consideration. The model gives us a consistentdescription of the temperature dependence of the Brillouin frequency shift with theother quantities, the specific volume and the heat capacity.
