The Origin of the Knee in the Cosmic-ray Energy Spectrum

Abstract

A sudden steepening of the cosmic-ray energy spectrum ( the knee ) is observed at an energy of about 3 PeV (1 PeV = 10eV). The recent results on extensive air showers allow us to conclude that: a) the knee has an astrophysical origin; b) the ‘sharpness’ and the fine structure of the knee rule out ‘Galactic Modulation’ as the origin of the knee; c) most… (More)
