Title: An Angular Force Model For Lattice Dynamics Of Body Centered Cubic Metals
Author: Shukla M.M.
Tejima H.
Abstract: A phenomenological model for lattice dynamics of b.c.c. metals is proposed by combining central ion-ion interaction on BVK scheme, angular ion-ion interaction on Clark-Gazis-Wallis scheme and electron-ion interaction on Krebs's scheme with an essential modification of the dielectric screening function. Calculated phonon dispersion curves of sodium along all the five principal symmetry directions as well as (Θ-T) curve of it show a good agreement with the experimental findings. © 1976 with the authors.
