Measurement of Cosmic-Ray Proton and Antiproton Spectra at Mountain Altitude
T. Sanuki, M. Fujikawa, H. Matsunaga +22
Cosmic-ray proton and antiproton spectra were measured at mountain altitude, 2770 m above sea level. We observed more than 2 x 10^5 protons and 10^2 antiprotons in a kinetic energy…

Measurements of atmospheric muon spectra at mountain altitude
T. Sanuki, M. Fujikawa, K. Abe +26
We report new measurements of the atmospheric muons at mountain altitude. The measurement was carried out with the BESS detector at the top of Mt. Norikura, Japan. The altitude is…

Measurements of Cosmic-ray Low-energy Antiproton and Proton Spectra in a Transient Period of the Solar Field Reversal
Y. Asaoka, Y. Shikaze, K. Abe +39
The energy spectra of cosmic-ray low-energy antiprotons and protons have been measured by BESS in 1999 and 2000, during a period covering the solar magnetic field reversal. Based o…
