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

At the Yakutsk EAS array Eem is determined by using measurements of EAS Ĉerenkov light flux and charged particle flux. It is known from calculations that these characteristics depend on a sort of primary particle and, therefore, the estimation of Eem depends on a primary particle mass. In the work t...

Description
Summary:At the Yakutsk EAS array Eem is determined by using measurements of EAS Ĉerenkov light flux and charged particle flux. It is known from calculations that these characteristics depend on a sort of primary particle and, therefore, the estimation of Eem depends on a primary particle mass. In the work the dependence of the Eem/E0 ratio on the energy is given and experimental data are compared with calculations by the QGSJET model. The calculations have been carried out for the primary proton and iron nucleus. The average calculated meaning of the value of Eem/E0 ratio (between the proton and iron nucleus) within experimental errors is in agreement with experimental data that doesnt contradict to the mixed mass composition of primary cosmic radiation.
