Abstract

The lattice parameters and thermal displacements in the γ → α phase transition of Ce was investigated for. Using the framework of electron-phonon coupling, it was observed that the bulk modulus follows a power-law pressure dependence. The energy for the phase transition was provided by the kinetic energy of the itinerant f electron. the results show that in addition to electronic and spin instabilities, lattice dynamics and electron-phonon coupling are essential elements for the study of the γ → α phase transition in elemental Ce.
