Abstract

One of the parameters of interest in studies on dilute alloys is the ratio of the effective host-host to impurity-host interaction. A method is presented which allows the evaluation of the effective impurity-host force-constant ratio, A′/A, for substitutional, isolated, impurity atoms in a cubic lattice by combining recoilless-fraction data (Mössbauer effect) of the impurity atoms with x-ray– or neutron-diffraction data of the host lattice. With this method, values of A′/A are obtained for dilute 57Fe impurities in various hosts.
