The discovery of geomagnetically trapped cosmic ray antiprotons
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +61
The existence of a significant flux of antiprotons confined to Earth's magnetosphere has been considered in several theoretical works. These antiparticles are produced in nuclear i…
PAMELA Measurements of Cosmic-ray Proton and Helium Spectra
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +62
Protons and helium nuclei are the most abundant components of the cosmic radiation. Precise measurements of their fluxes are needed to understand the acceleration and subsequent pr…
The cosmic-ray electron flux measured by the PAMELA experiment between 1 and 625 GeV
PAMELA Collaboration, O. Adriani, G. C. Barbarino +64
Precision measurements of the electron component in the cosmic radiation provide important information about the origin and propagation of cosmic rays in the Galaxy. Here we presen…
