Valence Effect

The electric field gradient (q) and asymmetry parameter (η) are calculated for nontransitional dilute alloys of Al. The nonlocal model potential is used to evaluate the valence-effect contribution and the elastic continuum model is adopted to evaluate the size-effect contribution. Although the nonlocality of the model potential greatly modifies the valence-effect contribution, the valence effect alone does not explain the observed values of q and η. The size-effect contribution is found to be larger than the valence-effect contribution. The calculated and experimental values of q and η are found to be in close agreement for almost all the alloys, and these are found to be correlated to the magnitudes of effective charges on impurities. A comparison of q and η for Cu and Al alloys is also presented.
