The interaction between impurities of two solute elements in metal hosts leads to a non-random distribution of impurity atoms among the lattice sites. Experimental studies of this distribution provide quantitative information on the energy involved in the formation of an individual impurity-impurity pair. The perturbed angular correlation measurements performed with ^{111}In probe atoms and Mössbauer spectra of ^{57}Co are used to derive the interaction energy of In atoms with Mn and Co atoms introduced into silver matrix. It is demonstrated that In atoms attract Mn and Co atoms and in the case of In-Mn pair the interaction energy value was determined. The obtained results are discussed in the frame of the semiempirical model and the recent first principles theoretical calculations.
