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…
Observations of the December 13 and 14, 2006, Solar Particle Events in the 80 MeV/n - 3 GeV/n range from space with PAMELA detector
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +61
We present the space spectrometer PAMELA observations of proton and helium fluxes during the December 13 and 14, 2006 solar particle events. This is the first direct measurement of…
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…
