Abstract
Measurements of positron lifetimes in quenched aluminum +0.09 at.−% Mn single crystals reveal the existence of a long-lived component whose lifetime and intensity increases and decreases with increasing temperature, respectively. The component is attributed to the annihilation of positrons at voids in the sample formed during quenching.
