Temperature effect of positron annihilation in argon
Lifetime techniques have been used to measure the direct annihilation rate in Argon gas as a function of temperature. In order to accomplish this, a pressure chamber capable of holding 10 amagats of gas at 300°C was designed and constructed. The temperature of the Argon gas was varied between 140°K...
