Measurements of Atmospheric Antiprotons
K. Yamato, K. Abe, H. Fuke +21
We measured atmospheric antiproton spectra in the energy range 0.2 to 3.4 GeV, at sea level and at balloon altitude in the atmospheric depth range 4.5 to 26 g/cm^2. The observed en…

Measurements of Proton, Helium and Muon Spectra at Small Atmospheric Depths with the BESS Spectrometer
K. Abe, T. Sanuki, K. Anraku +32
The cosmic-ray proton, helium, and muon spectra at small atmospheric depths of 4.5 -- 28 g/cm^2 were precisely measured during the slow descending period of the BESS-2001 balloon f…
