Abstract : In order to provide clues as to the mechanisms by which some celestial sources generate huge amounts of energy, a series of balloon-altitude experiments were undertaken during 1969 and 1970. They measured gamma ray spectra, in the energy range 25 keV - 975 keV from discrete celestial sources including the Crab Nebula, Pulsars NP 0532 and PSR-0835-45, the center of our galaxy, radiogalaxies Virgo A and Centaurus A, as well as from the galactic sources Cyg XR-1, Sco XR-1, and Cen XR-4. Significant new information on these objects and their energy sources was obtained and is discussed. (Author)
