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 0.511 ψ-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 ψ-ray line source.
