The problem of the binding of a positron to negative hydrogen ion is treated by the variational method with a fourparameter trial function. The best values of the parameters yield a binding energy of 0.228 ev against the most favored mode of dissociation into hydrogen plus positronium. Pair annihilation from the ground state of similar bound H/sup -/e/sup +/ systems might be expected to contribute a principal component to the radiation from the annihilation of positrons in the alkali hydrides. The theory of positron annihilation is extended for application to this problem. The ground-state wave function yields a mean life against two-photon annihilation of about four times that for singlet positronium, the difference arising mainly out of spin considerations. The calculation of the angular correlation of the annihilstion radiation indicates a narrower peak than those observed in LiH and NaH. (auth)
