Abstract

Light scattering spectra of B₂O₃ glass were measured in the frequency range 20-7000 GHz at temperatures in the range of 15-300 K and are compared with those previously obtained for Ca_0.4K_0.6(NO₃)_1.4 (CKN). The low-frequency contribution of the fast relaxation susceptibility spectrum is found to show a power-law behavior with an exponent α=0.6, the latter being temperature independent in contrast to the finding in other inorganic glasses such as silica and CKN. Possible explanations of the spectral shape in B₂O₃ are considered.
