Abstract

Hyperfine interactions for Ta impurities in a polycrystalline nickel matrix produced by quenching from the melt have been studied using the perturbed-angular-correlation technique. An effective hyperfine field of -89.8 ± 1.6 kOe was measured for substitutional atoms. The fraction of the impurities occupying various lattice positions, and the respective hyperfine fields have been determined, and changes in lattice location and hyperfine field after annealing of the source have been studied.
