A NEUTRON INELASTIC SCATTERING STUDY OF PHONONS IN METASTABLE BETA-GALLIUM
Résumé
The phonon dispersion curves of C-centred monoclinic beta-gallium at the melting temperature have been measured along five symmetry directions. The behaviour of the lower longitudinally polarised branch in the Ex (Sx) direction suggests a desire to double the size of the unit cell. Initial model fitting calculations indicate that the interactions in ß-Ga are of reasonably long range.
