Frequency behavior of Raman coupling coefficient in glasses (2002)
Surovtsev, N. V., Sokolov, A. P.
Low-frequency Raman coupling coefficient of 11 different glasses is evaluated. It is found that the coupling coefficient demonstrates a universal linear frequency behavior near the boson peak maximum...
q-dependence of low-frequency Raman scattering in silica glass (1999)
Surovtsev, N. V., Wiedersich, J., Novikov, V. N., R"ossler, E., Duval, E.
Accurate measurements of the dependence of low-frequency Raman scattering on the scattering angle were performed in two silica glasses. By a comparison of spectra measured at a large scattering angle...
