Anharmonic properties of Li
Physical Review B (Condensed Matter)
The energies and lifetimes of phonons in metallic Li between 110 and 424 K are calculated using the selfconsistent phonon theory and the e6ective ion-ion interaction developed by Dagens, Rasolt, and Taylor (DRT). The results are compared with the recent neutron scattering measurements of Beg and Nielson. Li turns out to be surprisingly harmonic, less anharmonic than Na or K, due to the strong Li ion-ion interaction which has a relatively soft. repulsive core. The anharmonic corrections dodoi:10.1103/physrevb.18.2643 fatcat:6uuvw4iltzdrzeodpw6v5svd64
