TL;DR: The peak spectrum is reproduced by theoretical calculations, implying that the propagation models are basically correct and that different cosmic-ray species undergo a universal propagation.

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: Based on measurements, a sudden increase of the *p/p flux ratio following the solar magnetic field reversal was observed, and it generally agrees with a drift model of the solar modulation.
