Estimate of the Mass Composition of Ultrahigh Energy Cosmic Rays
A. A. Mikhailov, N. N. Efremov, N. S. Gerasimova +3
It is proposed a new approach for estimating the composition of cosmic rays. It is found that the zenith angle distributions and muon components of EAS for energies E>10^19 eV and…

Deficit of Ultrahigh Energy Extensive Air Showers
A. A. Mikhailov, N. N. Efremov, I. T. Makarov +2
Arrival directions of extensive air showers by using world data are considered. It is shown that distributions of showers in zenith angle at E>10^{19}eV and E>4.10^{19}eV differ fr…
