dc.description.abstract	The astrophysical importance of the negative positronium ion, detected recently in the laboratory, has been pointed out. It is found that the presence of Ps(-) ions will contribute additionally to the width of the 0.511 gamma-ray line formed by pair annihilation. The formation of Ps(-) ion from an aggregate of electrons, positrons and positronium results in a variable positron population in the 0.511 MeV gamma-ray line source.	en
