Composition of Cosmic Rays with the Energy more than 4x10^{19} eV
Arrival directions of extensive air showers by using world data are considered. It is found that the shower distribution in zenith angle at the energies E>10^{19} eV and E>4x10^{19} eV differs from each other. By our estimations, the shower with E>10^{20} eV at the Sugar array was not regis...

Summary: | Arrival directions of extensive air showers by using world data are considered. It is found that the shower distribution in zenith angle at the energies E>10^{19} eV and E>4x10^{19} eV differs from each other. By our estimations, the shower with E>10^{20} eV at the Sugar array was not registered. The mass composition of very high-energy cosmic rays has been estimated. It is shown that E>4x10^{19} eV cosmic rays are, most likely, super heavy nuclei with charge Z>26. : 5 pages, 4 figures. Contributed talk presented at 28-th ICRC, Thusuba, Aug., 2003; Sem. Inst.
