Özet:

 

Recently proposed pseudopotential has been used to calculate  asphericity in the Fermi surface of d and f-shell metals along the  three symmetry directions [100], [110] and [111].  The parameter of  the potential has been determined by zero pressure condition and the  exchange and correlation function due to Taylor has been incorporated.  The present results are in good agreement with experimental findings  for Cu, Ag, Au and Pd; while for other d and f- shell metals we could  not found sufficient theoretical as well as experimental data for the  asphericity in the Fermi Surface in order to workout a quantitative  comparison.  It, therefore, seems difficult to give concrete remark  about the present results.  We conclude that the calculations of  asphericity in the Fermi Surface based on pseudopotential theory can  be regarded as a sensitive test for the proper assessment of the  pseudopotential form factor.  A successful application to the  asphericity in the Fermi Surface confirms the ability of model  potential for predicting wide range of physical properties of  transition metals.
