The very accurate data show that the positron fraction is steadily increasing from 10 to ∼ 250 GeV, but, from 20 to 250 GeV, the slope decreases by an order of magnitude, showing the existence of new physical phenomena.

Measurements by the Alpha Magnetic Spectrometer on the International Space Station of the primary cosmic-ray electron flux and the positron flux are presented and the determination of the differing behavior of the spectral indices versus energy is a new observation and provides important information on the origins of Cosmic-ray electrons and positrons.
Precision Measurement of the Helium Flux in Primary Cosmic Rays of Rigidities 1.9 GV to 3 TV with the Alpha Magnetic Spectrometer on the International Space Station.

In the absolute rigidity range ∼60 to ∼500 GV, the antiproton p[over ¯], proton p, and positron e^{+} fluxes are found to have nearly identical rigidity dependence and the electron e^{-} flux exhibits a different rigidity dependent.
