Description

The energy spectrum of the cosmic radiation in the range 10**19-2.4x10**21 eV has been recently predicted showing a rich and distinctive staircase profile. In order to check the prediction, the spectra measured by running and past experiments above 10**19 eV are examined. The computed spectrum compares more favourably with the Telescope Array data rather than with the Auger data in the range 10**19-2x10**20 eV. Previous measurements by Haverah Park, Fly’s Eye, HiReS, Yakutsk and AGASA experiments in the limited band 10**19-3x10**20 eV are scattered above the computed energy spectrum by a factor 2-5 in units of particles/m**2 sr s GeV**1.67. Auger data points on the spectrum in the interval (5-10)x10**19 eV are below those of all previous experiments by about an order of magnitude and below those of Telescope Array experiment by a factor 5. Presently, the spreads in the quoted measurements foreclose a complete validation of the predicted spectrum and the principles from which it is derived.
