Abstract
The problem of lattice dynamics of transition metals is investigated. For the case of paramagnetic nickel, the isotropic two-band model is used to evaluate the static dielectric function in the Hartree approximation. The bare-ion potential is represented by a two-parameter model potential. The phonon frequencies are calculated for the configurations (3d)9(4s)1 and (3d)9.4(4s)0.6, and compared with the experimental measurements along the three principal symmetry directions [100], [110], and [111]. A fairly good agreement is obtained for both configurations.
