Beschreibung:
Results are presented from a balloon-borne apparatus searching for low-energy antiprotons in the Galactic cosmic rays. For energies less than 640 MeV at the top of the atmosphere, no cosmic-ray antiprotons were observed. This yields an upper limit to the antiproton/proton ratio of 0.000046 at the 85-percent confidence level.
