Search for Cosmic-Ray Antideuterons
H. Fuke, T. Maeno, K. Abe +23
We performed a search for cosmic-ray antideuterons using data collected during four BESS balloon flights from 1997 to 2000. No candidate was found. We derived, for the first time,…

Successive Measurements of Cosmic-Ray Antiproton Spectrum in a Positive Phase of the Solar Cycle
T. Maeno, S. Orito, H. Matsunaga +1
The energy spectrum of cosmic-ray antiprotons has been measured by BESS successively in 1993, 1995, 1997 and 1998. In total, 848 antiprotons were clearly identified in energy range…

Measurement of Low-Energy Cosmic-Ray Antiprotons at Solar Minimum
H. Matsunaga, S. Orito, H. Matsumoto +21
The absolute fluxes of the cosmic-ray antiprotons at solar minimum are measured in the energy range 0.18 to 1.4 GeV, based on 43 events unambiguously detected in BESS '95 data. The…
