Abstract: A modification of the form of Shaw's optimized model potential is proposed so as (a) to decrease the energy dependence of the model potential parameters and (b) to increase the flexibility, and thereby the applicability, of the model potential. Calculations of the Fermi surface distortions of K, Rb and Cs metals using the present proposed model pseudopotential show significant improvements in the results over those obtained from Shaw's optimized model potential. The phonon dispersion relations of K, Rb, Cs an…
