摘要：

In this paper we consider the possibilities for producing a dense gas of N congruent-to 10(5) triplet positronium (Ps) atoms in vacuum contained in small cavity V congruent-to 10(-13) cm3. We then consider the scenario where this dense gas of polarized Ps atoms may cool through a weakly interacting Bose transition. The rates for thermalization with the wall, equilibrium in the bulk, and loss of polarization by exchange collisions are calculated. A method for observing the transition is also discussed.
