Phys. Rev. B 49, 454–458 (1994)Possibilities for Bose condensation of positroniumReceived 2 September 1993; published in the issue dated 1 January 1994 In this paper we consider the possibilities for producing a dense gas of N≃105 triplet positronium (Ps) atoms in vacuum contained in small cavity V≃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. © 1994 The American Physical Society URL:
