Behavior of some characteristics of EAS in the region of knee and ankle of spectrum

TL;DR

This paper investigates specific characteristics of extensive air showers (EAS) in the knee and ankle regions, analyzing energy-dependent ratios related to charged particles, muons, and electromagnetic components, and compares them with cosmic ray composition models.

Contribution

It introduces an analysis of EAS characteristics in the knee and ankle regions and compares observational data with QGSJET model predictions for different cosmic ray compositions.

Findings

Energy-dependent ratios of EAS characteristics are presented.

Comparison with p-Fe cosmic ray models shows consistency or discrepancies.

Results contribute to understanding cosmic ray composition at high energies.

Abstract

The energy dependence of such characteristics as a ratio of the total number of charged particles to the total flux of EAS Cherenkov radiation, a ratio of E(thr)>=1GeV muon flux density at the distance of 600m from a shower core to charged particle flux density, a ratio of the energy transferred to the electromagnetic component of EAS to the primary particle energy is presented. Their comparison with two-component mass composition of cosmic rays (p-Fe) in the framework of calculations by a QGSJET model is given.
