Giant air showers: The problem of events with E-0 >= 10(20) eV

摘要

The problem of the "upper edge" of the energy spectrum of giant air showers (GASs) with E-0 greater than or equal to 10(19) eV is considered. The almost complete absence of GASs with the highest energies (E-0 greater than or equal to 10(20) eV) at the Yakutsk array and their considerable number at AGASA are discussed in view of the fact that both arrays have similar basic detectors and similar procedures of data processing are being used.
