Search for Gamma-Ray Continuum Emission at MeV Energies from the Galactic Center Region
Abstract
From balloon flight data of the MPE Compton telescope, constraints on the continuum emission of the Galactic center region at MeV energies were derived. The Galactic center point source flux was found to be less than 2.8×10-3cm-2s-1 between 0.6 to 3.0 MeV, which implies that the source was in a "low-intensity state" during the time of the observation (1982 October 31). The diffuse γ-ray flux from the central region of the Galactic plane was determined to be smaller than 7.2×10-3cm-2s-1rad-1 at l = 0 in the same energy interval.
