摘要：
In the present work, a microscopic study of the phonon dispersion in Tb is made in the nonlocal scheme of Eschrig and Wonn. In contrast to earlier workers who use the nonlocal q-dependent parameters as adjustable constants, we use actual functional expressions of these parameters in the calculations. The results are in a reasonably good agreement with experimental data.
