Description
Summary:It is proposed that the energy of inclined extensive air showers be estimated using signals from the surface scintillation detectors of the Yakutsk array, located at a distance of 600 m from the shower axis and the zenith angle of shower arrival. Estimates of the energy of inclined showers are calculated using new formulas obtained from simulations using different models of hadron interaction. These models of hadron interaction are validated by comparing calculated and experimental spectra of atmospheric muons. It is found that the muon spectrum calculated with the EPOS LHC and QGSJETII-04 models differs little from the experimental spectrum. It is shown for the first time that the energy spectrum of primary cosmic radiation is in good agreement with the literature data.
