英文摘要
The Balloon-borne Experiment with t Superconducting magnet Spectrometer (BESS) has been carried out in a collaboration amongst High Energy Accelerator Research Organization, University of Tokyo, Kobe University, Institute for Space and Astronautical Science. The ballooning has been supported by NASA balloon project office.Search for cosmic-ray antiprotons has been carried out, and more than 400 cosmic-ray ntiprotons have been detected in an energy range of 0.5-1 GeV with the definitive identification by direct mass measurement.Search for antihelium has been also made and no candidates have been detected in a rigidity range below 16 GV with the possible upper limit of 3x10^<-6> in He-bar/He ratio. Those results have been published partly already published in Physical Review Letters and The Astrophysical Journal
