Electronic structure of metals. II. Phonon spectra and Fermi surface distortions

Abstract
For pt.I see ibid., vol.5, p.1836 (1975). The energy independent model pseudopotential (EIMP) formalism, developed in the preceding paper, and Shaw's optimized model potential (OMP) formalism are applied to first principles calculations of phonon spectra of the alkali metals and Al and of Fermi surface distortions for the alkali metals. Further, when compared with existing APW calculations for Fermi surface distortions, the relativistic effects due to the deep-core electrons, which is taken into account implicitly through the model potential parameters in the EIMP calculation, are found to be rather significant for heavier metals.
