TL;DR: In this article, the BESS-TeV spectrometer was used to precisely measure the primary and atmospheric cosmic-ray spectra with a high resolution of 7 times higher resolution in momentum measurement, and the absolute fluxes of primary protons and helium nuclei in the energy ranges, 1.540 and 1.250, respectively, were reported.

TL;DR: The magnetic rigidity of the cosmic-ray proton and helium spectra was reliably determined by highly precise measurement of the circular track in a uniform solenoidal magnetic field of 1 Tesla as discussed by the authors.

TL;DR: The magnetic rigidity of the cosmic ray was reliably determined by highly precise measurement of the circular track in a uniform solenoidal magnetic field of 1 T in 1998 as discussed by the authors, and the cosmic-ray proton and helium spectra were determined within overall uncertainties of ±5% for protons and ±10% for helium nuclei including statistical and systematic errors.

TL;DR: In this paper, the authors measured low energy cosmic-ray proton and helium spectra in the kinetic energy range 0.215-21.5 GHz at different solar activities during a period from 1997 to 2002.

TL;DR: A search for cosmic-ray antideuterons using data collected during four BESS balloon flights from 1997 to 2000 found no candidate and derived an upper limit of 1.9 x 10(-4) (m2s sr GeV/nucleon)(-1) for the differential flux at the top of the atmosphere.
