摘要
A detailed study of asphericity in the Fermi surface of aluminium (Al) and lead (Pb) along three symmetry directions [100], [110] and [111] is made on the basis of pseudopotential theory extending upto second order. The influence of exchange and correlation effects on the asphericity in the Fermi surface is examined explicitly by using four different forms of screening function. For polyvalent metals Al and Pb the distortion in the Fermi surface is found to be sensitive in regard to various local field corrections. Copyright (C) 1996 Elsevier Science Ltd
