Abstract
A study aimed at calculating the probability of a nonthermalized positron being localized at a thermally generated defect is examined. We find that by utilizing the theoretical works of Perkins and Carbotte and McMullen and Stott a significant fraction of positrons are localized before reaching equilibrium with the lattice. These results are compared with both bulk positron lifetime and variable-energy positron data. Implications of these results are discussed.
