Abstract
By applying the positron trapping model (PTM) for metal Al with monovacancy, divacancy, detrapping effect of positron for monovacancy, the formation energy of monovacancy and divacancy are estimated. By using the value of formation energy of divacancy in the case with the trap rate depends on temperatur is E_d^F=0,956 ± 0,120 (eV) the fraction of concentrate of divacancy is estimated at differently temperatures. These results are available for researching stable structure of metal Al and its alloy.
