Abstract
A more realistic model, requiring a few parameters to explain the interactions among distant neighbours and valid for various crystallographic structures, is developed to study phonon dispersion in the bulk fcc metals. The model free from usual fitting procedure is employed to obtain phonon-dispersion in the bulk of fcc strontium crystal which has attracted scant attention so far. The computed results showing good agreement with the recent experimental results lend reliability and credibility to the theory.
