Description
The GSFC Low-Energy Gamma-Ray Spectrometer observed the galactic center on 20 November, 1981, during a balloon flight from Alice Springs, Australia. The positron annihilation line at 511 keV showed no excess over background when the galactic center was in the field-of-view; the inferred upper limit to the intensity of such a features is 1.2 x 10-3 photons/cm2-s (95 percent confidence). Continuum emission was observed between 70 keV and 1 MeV
