Deficit of Ultrahigh Energy Extensive Air Showers
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 from each other. On this basis the conclusions are made: the estimation of the energy of inclined showers at E>4....

| Summary: | 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 from each other. On this basis the conclusions are made: the estimation of the energy of inclined showers at E>4.10^{19}eV at Yakutsk and AGASA arrays is incorrect; the cosmic ray spectrum is not break up and most likely continued up to E=10^{20}eV and higher. It is found that ultrahigh energy cosmic rays are, probably, superheavy nuclei. : 4 pages, 4 figures. The paper will be published in Proc. 28-th Russian conf. on cosm. rays, Moscow, 2004 |
