Abstract

Phonon dispersion relations for the normal modes of lattice vibration inbcc transition metals are computed along the three principal symmetry directions using the extended form of theFielek five-constant model. The calculated results are compared with the available experimental data obtained from inelastic neutron spectroscopy and a far better agreement than that obtained on the basis of other existing models has been achieved.
