INFLUENCE OF PRIMARY COSMIC RADIATION MASS COMPOSITION ON THE ESTIMATION OF EAS ENERGY

Energy portion Eem/E0 transferred to EAS electron–photon component at E0 = 10 15 ± 10 19 eV was estimated by using of Čerenkov radiation data and charged particles data obtained at the Yakutsk array. The results are compared with the models for different energy dissipation into EAS electron– photon...

Description
Summary:Energy portion Eem/E0 transferred to EAS electron–photon component at E0 = 10 15 ± 10 19 eV was estimated by using of Čerenkov radiation data and charged particles data obtained at the Yakutsk array. The results are compared with the models for different energy dissipation into EAS electron– photon component and with calculations for different primary nuclei. In the energy intervals 10 15 ± 10 16 eV and 10 18 ±10 19 eV Eem/E0 is equal to (77 ±2) and (88 ±2) % respectively, that doesn’t contradict with mixed composition of primary particles for the first energy interval and the proton composition for the second one.
