Clusters of Cosmic Rays above 4.10^19 eV
A. A. Mikhailov, N. N. Efremov
Arrival directions of cosmic rays with the energy E>4.10^19 eV are analyzed on the basis of the Yakutsk and AGASA extensive air shower arrays. It is supposed that the clusters can…

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…

Extensive air showers without muon component
A. A. Mikhailov, N. N. Efremov, E. S. Nikiforova
Extensive air showers of cosmic rays with energies above 5.10**18 eV registered by the Yakutsk array have been analyzed. The existence of showers without muon component is found. A…
