Abstract

Results of measurements of the energy characteristics of muon bundles in inclined extensive air showers in the NEVOD-DECOR experiment are presented. Estimates of the average energy of muons in the bundles in the energy range of primary particles from 10 to 1000 PeV were obtained and compared with the calculated expected values for various assumptions about the composition of cosmic radiation and models of hadronic interactions. An excess of experimental values of the average muon energy in comparison with calculations for high local densities corresponding to energies of primary particles above 100 PeV was found.
