✦ Synopsis
The temperature dependence of positron annihilation in copper and a 0.3 at. "/b AgSb alloy has been investigated by measuring the positron lifetime. I n both cases the vacancy lifetime is nearly independent on temperature while the bulk lifetime shows a rapid increase after the onset of detectable vacancies. This increase can be explained by trapping during thernialization with a n enhanced trapping rate. l ) Contributed paper presented during the European Meeting on Positron Studies of
