Anharmonic Self-Energy of Phonons: Ab Initio Calculations and Neutron Spin Echo Measurements

A. Debernardi, F. de Geuser, J. Kulda +2

We have calculated (ab initio) and measured (by spin-echo techniques) the anharmonic self-energy of phonons at the X-point of the Brillouin zone for isotopically pure germanium. Th…
