Hard X-rays as pump and probe of atomic motion in oxide glasses
B. Ruta, F. Zontone, Y. Chushkin +5
Nowadays powerful X-ray sources like synchrotrons and free-electron lasers are considered as ultimate tools for probing microscopic properties in materials. However, the correct in…
Vitreous silica distends in helium gas: acoustic vs. static compressibilities
Coralie Weigel, Alain Polian, Mathieu Kint +3
Sound velocities of vitreous silica are measured under He compression in the pressure range 0-6 GPa by Brillouin light scattering. It is found that the well-known anomalous maximum…
VUV Brillouin scattering from superpolished vitreous silica
B. Rufflé, E. Courtens, M. Foret
A previous inelastic UV scattering experiment on silica glass is reproduced using a high grade superpolished sample. In the pristine sample condition, surface scattering is not obs…
Eliminating the broadening by finite aperture in Brillouin spectroscopy
R. Vialla, B. Rufflé, G. Guimbretière +1
We present a new optical arrangement which allows to avoid the broadening by finite aperture in Brillouin spectroscopy. In this system, all the rays scattered at the same angle by…
