Direct Measurement of the Nickel Spectrum in Cosmic Rays in the Energy Range from 8.8 GeV/n to 240 GeV/n with CALET on the International Space Station

O. Adriani, Y. Akaike, K. Asano +78

The relative abundance of cosmic ray nickel nuclei with respect to iron is by far larger than for all other trans-iron elements, therefore it provides a favorable opportunity for a…

Helium fluxes measured by the PAMELA experiment from the minimum to the maximum solar activity for solar cycle 24

N. Marcelli, M. Boezio, A. Lenni +53

Time-dependent energy spectra of galactic cosmic rays (GCRs) carry fundamental information regarding their origin and propagation. When observed at the Earth, these spectra are sig…
