Dependence of the Energy Spectrum of UHE Cosmic Rays on the Latitude of an Extensive Air Shower Array

摘要

Several energy spectra of cosmic rays with energies E_0 \geq 10^17 eVmeasured at the Yakutsk EAS, AGASA, Haverah Park, HiRes, Auger, and SUGARarrays are considered. It is shown that the fairly good mutual agreement of thespectrum shapes can be achieved if the energy of each spectrum is multiplied bya factor K specific for each spectrum. These factors exhibit a pronounceddependence on the latitude of the above-mentioned arrays.
