| The monovacancy formation energy in Sn-17 wt.% In and Sn-32 wt.% In was determined on the basis of the temperature dependence of the peak counting rate for these alloys. A sudden increase in the counting rate was observed between solidus and liquidus temperature. This phenomenon is connected with the formation of large defects acting as positron traps. |
