Abstract
The mean life of the long-lived component of positrons annihilating in various solids and liquids has been measured at pressures up to 6000 atm and temperatures up to 200°C. At fixed temperature, the mean life decreases exponentially with the change in volume due to increasing pressure. At fixed volume, the lifetime decreases with increasing temperature. A qualitative explanation of the variation is presented.
