| Abstract: | The electric field gradient (EFG) and the asymmetry parameter (η) due to transition metal impurities in the host metals Al,
Cu and V are investigated. The valence EFG is formulated using dielectric screening theory in conjunction with pseudopotential
theory. The size EFG is evaluated in the elastic continuum limit for a screened point charge model of the host metal. The
detailed calculations are carried out forAl (Sc, Fe, Cr),Cu (Ni, Pd, Pt) andV (Ti, Cr, Fe, Nb, Ta, W) alloys. |
