The effects of the physical aging on the vibrational density of states (VDOS) of a polymeric glass is studied. The VDOS of a poly(methyl methacrylate) glass at low-energy (

Comparisons are made between the low-frequency Raman and inelastic neutron-scattering spectra obtained from amorphous bisphenol A polycarbonate at low temperature. The vibrational density of states and light-vibration coupling coefficient are determi

The temperature dependences of the self-diffusion coefficient and the spin-lattice relaxation time have been studied by NMR measurements performed on a good glass former LiCl-6H 2 O. The spin-lattice relaxation time can be separated into two relaxati

In poly(methyl methacrylate) glass at temperatures much lower than the glass transition temperature, one observes quadielastic light or neutron scattering. The corresponding relaxation time is short (about 4 × 10−12s) and weakly dependent on tempe

The difference methods of neutron diffraction and isotopic substitution were applied to and in the aqueous lithium chloride glass at 120 K (the glass transition ). Results for the ionic hydration show that structural changes are more evident for the

Fast relaxational motions in glassy PMMA were investigated through quasielastic neutron scattering. As previously found with quasielastic light scattering, the corresponding relaxation time, which is of the order of 10−11 s, is only slightly temper

A deeper insight into short, medium and long ranges behaviour of partial structure factors (PSF) measured in the rich metal domain of KxKCL(l-x) solutions as a function of composition shows up that structural changes are characterised by a non-linear
