摘要：

A hollow spherical bubble containing thousands of spin-aligned triplet positronium (Ps) atoms in superfluid liquid He-4 would be stable against breakup into smaller bubbles, and the Ps would form a Bose-Einstein condensate (BEC) with a number density of similar to 10(20) cm(-3) and a BEC critical temperature T-c approximate to 300 K. Estimates suggest that one could make such bubbles in the laboratory containing 10(5) Ps atoms using presently known methods.
