Abe, K., Sanuki, T., Anraku, K., Asaoka, Y., Fuke, H., Haino, S., ...

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 flight. The...

Atmospheric gamma-ray observation with the BETS detectorfor calibrating atmospheric neutrino flux calculations (2002)
