✦ Synopsis

Inelastic neutron scattering measurements of phonon spectra from a powder sample of fayalite at various temperatures is reported. The measured spectra have been satisfactorily analyzed on the basis of a lattice dynamical model. The phonon density of states is used to derive the specific heat, which are found to be in good agreement with experimental data.

Inelastic neutron scattering measurements and rigid-ion model calculations of phonon dispersion relation in the geophysically important mineral fayalite is reported. The measured r. 4 TA branch is found to be softer in fayalite as compared to that in forsterite Mg2SiO 4. The rigid-ion model calculat
