“…2) on the phonon dispersion in f.c.c. thorium show good agreement with the experimental findings of Reese et al [23]. The present model has earlier predicted the cohesive energy and therefore, explains all the qualitative features of phonon dispersion relations of the said metal.…”

“…While the phonons between ξ=0.4 and 0.6 show a large energy increase with pressure, the phonon energy decreases at the zone boundary, thus leading to a pronounced overbending of the branch. The shape of the LA phonon branches in the α-phase are close to those measured in thorium at ambient conditions [2] while the γ-phase phonon dispersion resembles fcc metastable lanthanum [3]. This behaviour might be a signature of substantial changes in the Fermi surface topology, leading to significant changes in the electron-phonon coupling mechanism.…”

“…6). Comparison of the phonon dispersion curves with those of thorium [81] shows that the spectrum of -cerium is in general softer (i.e. its vibration frequencies are smaller) than one expects from the Lindemann criterion for melting.…”
