| Abstract: | A lattice dynamical model for bcc metals, which satisfies the internal force equilibrium condition of the lattice is proposed.
The present model combines a linearized Thomas-Fermi Theory for the electron-ion interaction and the central pair potential
for ion-ion interaction. as an application, the computed phonon dispersion, vibrational spectrum, and lattice specific heat
of tantalum show fairly good agreement with experiments. |
