Superconducting MgB$_2$ shows an E$_{2g}$ zone center phonon, as measured by Raman spectroscopy, that is very broad in energy and temperature dependent. The Raman shift and lifetime show large differences with the values elsewhere in the Brillouin Zo

We present a combined experimental and theoretical investigation of the lattice dynamics and electron–phonon coupling of the ternary silicides MAlSi (M = Ca, Sr, Ba). Temperature dependent inelastic neutron-scattering measurements of the generalize

We report on recent Raman- and inelastic neutron scattering measurements on Mg 1-x Al x B 2 , LiBC and TMB 2 (TM = transition metal). All materials crystallize in the AlB 2 structure and show in particular for MqB 2 a pronounced anharmonic behavior f

The corrosion of directly disposed spent nuclear fuel by contact with intruding groundwater will alter the physical and chemical properties of this material. Secondary phases which formed during alteration of UO 2 surfaces were measured with Raman mi

Using inelastic neutron scattering we have investigated the external mode spectrum of solid ${\mathrm{C}}_{60}$ in the orientationally ordered phase. Hydrostatic pressures 1 bar $lPl9$ kbar and temperatures $180 \mathrm{K}lTl335$ K were covered. The
