Using the ITC technique the dielectric relaxation of KI doped with divalent ions and small amounts of Cl − or Br − anions is studied. New low temperature ITC peaks are found at temperatures as low as 120 K. Also a strong effect is found in the aggregation kinetics of the divalent ions. A model for the trapping of the divalent ions by the Cl − or Br − anions is proposed.
