Positron-Dislocation Interaction in Deformed Zn and Cd

Abstract: The evolution of the positron lifetime parameters with temperature is studied in deformed Zn and Cd in the temperature range 12 to 210 K. The presence of a trapping component with a lifetime of 230ps in Zn and250ps in Cd was observed. The intensity of the long component decrease drastically with increasing temperature These results are discussed in the framework of the trapping model for dislocations in which it is assumed indirect positron trapping into deep traps (jogs orland vacancies) through shallow traps… Show more
