Cosmic ray spectrum by energy scattered by EAS particles in the atmosphere and galactic model

TL;DR

This paper compares cosmic ray energy spectra from Cherenkov radiation measurements with an anomalous diffusion model, finding good agreement and consistent mass composition estimates across a wide energy range.

Contribution

It introduces a comparison between experimental cosmic ray spectra and a fractal-based diffusion model, supporting the model's validity in explaining cosmic ray propagation.

Findings

Good agreement between measured and modeled spectra from 10^15 to 10^18 eV.

Mass composition estimates are consistent with experimental data.

Supports fractal anomalous diffusion as a viable model for cosmic ray propagation.

Abstract

The differential energy spectrum of cosmic rays from Cherenkov radiation measurements in EAS in the energy range of 10^15-10^20eV has been compared with an anomalous diffusion model for the particles in interstellar space having fractal properties (Lagutin et al, 2001). The close association between experimental data and calculated "all particle" spectra in form at E(0) (10^15-10^18)eV is found. In this case, the average mass composition of cosmic rays calculated by five components does not contradict the average mass composition from experimental data which was obtained by several of EAS characteristics in that energy region.
