Abstract Results of a series of experiments to detect gamma-ray emission greater than 10 MeV from the Galactic plane near the Galactic center are reported. Three low-background observations of the Galactic center region were made from high-altitude balloon platforms at approximately 12 GV geomagnetic cutoff rigidities in 1971 and 1975. A 3 deg wide band of emission along the plane was detected near the center which shows clustering on the 1 deg scale of the instrument's resolution. A significant part of this narrow band of emission is either from a concentrated region of diffuse emission between 350 deg and 0 deg Galactic longitude or from up to five discrete sources. Support for this discrete source interpretation comes from the fact that five of the seven most significant event concentrations correlate in position with five of the seven previously detected hard X-ray and higher energy gamma-ray sources in the Galactic center region.
