The crystalline quality of GaAs and InP single crystals grown by the liquid-encapsulated Czochralski technique, was investigated by γ-ray diffraction. In particular, the rocking curve was measured in different areas of each crystal, obtaining the mo

We report X-ray and neutron scattering results in vitreous silica. As in earlier data, clear evidence is found for sound wave modes at the energies of the boson peak. We have observed by X-ray experiments a clear dispersion of Brillouin peaks and we

Neutron scattering has been used to study the magnetic correlations and the spin dynamics in the ferromagnetic lanthanum-manganite La0.75Ca0.25MnO3 above and below the Curie temperature. This material is known to exhibit colossal magnetoresistence be

New coherent inelastic neutron scattering measurements on silica xerogels in the 300–1000 K temperature range are presented and compared with those obtained in vitreous silica (heralux). The spectra show the presence of the Boson peak, at temperatu

We have performed inelastic and quasielastic neutron-scattering experiments (IQENS) on the highly lithium doped fulleride ${\mathrm{Li}}_{12}{\mathrm{C}}_{60}$ covering the T range from 150 to 600 K, across a tetragonal to cubic fcc phase transition

We present results on the dynamics of the Li+ ions and of the C60 molecular units in Li12C60 obtained by INS and QENS experiments performed on IN6 (at the Institut Laue-Langevin) covering the temperature range 150K to 600 K. The transition from the h

Microstrip gas counters with a very small gap between anode and cathode have a very stable gas amplification even if this gap is charged up or if its surface resistance is changed by ageing.
