Abstract:
The responses of ground and underground muon scintillation detectors of the Yakutsk extensive air shower (EAS) array from primary particles with the energy $E_0\geq10^{17}\,$eV have been calculated within the QGSJET-01-d, QGSJET-II-04, SIBILL, and EPOS-LHC models with the CORSIKA package. A new estimate obtained for $E_0$ is lower by a factor of about $1.41$ than that previously obtained within the calorimetric method for EASs.
