Transition from Galactic to Extra-Galactic Cosmic Rays

天体物理学 2009-11-11 v1

摘要

In this paper we review the main features of the observed Cosmic Rays spectrum in the energy range 1017eV ÷ 1020eV10^{17} {\rm eV}~\div~10^{20} {\rm eV}. We present a theoretical model that explains the main observed features of the spectrum, namely the second Knee and Dip, and implies a transition from Galactic to Extra-Galactic cosmic rays at energy E1018E\simeq 10^{18} eV, with a proton dominated Extra-Galactic spectrum.
