Abstract We present a description of the probe-impurity distant neighbours configuration for repulsive systems in a cubic lattice, using a continuous charge distribution around the probe nuclei. We propose a simple model for the charge distribution shape and its dependence with the impurity concentration. TDPAC measurements performed on111Cd probes in 1, 4, 7 and 20 at%AgIn alloys are reported and analyzed in the light of our model. In particular, the results suggest that impurities tend to form a cubic super-lattice with increasing concentration. Improvements to the model are discussed in connection with the possibility of getting quantitative information (like repulsive energies) from TDPAC measurements on repulsive systems.
