title = "Measurements of proton, helium and muon spectra at small atmospheric depths with the BESS spectrometer",
abstract = "The cosmic-ray proton, helium, and muon spectra at small atmospheric depths of 4.5-28 g/cm2 were precisely measured during the slow descending period of the BESS-2001 balloon flight. The variation of atmospheric secondary particle fluxes as a function of atmospheric depth provides fundamental information to study hadronic interactions of the primary cosmic rays with the atmosphere.",

note = "Funding Information: We would like to thank NASA and the National Scientific Balloon Facility (NSBF) for their professional and skillful work in carrying out the BESS flights. We are indebted to M. Honda and T. Kajita of ICRR, the University of Tokyo for their kindest cooperation for Monte Carlo simulations and theoretical interpretations. We would like to thank ISAS and KEK for their continuous support and encouragement for the BESS experiment. The analysis was performed with the computing facilities at ICEPP, the University of Tokyo. This experiment was supported by Grants-in-Aid (12047206 and 12047227) from the Ministry of Education, Culture, Sport, Science and Technology, MEXT.",
