RESUMO

The present thesis consists of modifying the point ion tensor force model as far as the inclusion of the electron-ion interaction is concerned.This scheme has been applied for almost all b.c.c. metals by calculating the phonon dispersion relation along symmetry directions, lattice heat capacities and Debye equivalent temperature. The theoretical results compare favorably well with the experimental observation indicating, thus, the correctness of our theoretical approach of modifying tensor force model
