Energy Spectra of Light Species of Primary Cosmic Rays in the Energy Range from 100 GeV to 100 PeV

Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

Experimental results obtained a few decades ago associate the knee with the bending of the light component (p and He), and are compatible with a rigidity-dependent cut-off at 3–5 PeV. On the contrary, new experiments obtained by arrays located at high altitudes indicate that the light component cuts off well below 1 PeV. We re-analyze the energy spectrum of light nuclei obtained by the MAKET-ANI experiment at Aragats Mt. in Armenia and put them in the context of new experimental evidence.
