Abstract

The energy spectrum of primary cosmic rays at energies between 2\(\times 10^{13}\) and 3\(\times 10^{17}\) eV is presented according to data from the Tien Shan array on the basis of the detection of the number of electrons in extensive air showers. In the energy range of \(5\times 10^{15}{-}3\times 10^{17}\) eV, the spectrum was obtained by means of the HADRON array and was extended to the region of lower energies from \(2\times 10^{13}\) eV on the basis of the results of an individual experiment. The changes in the slope of the spectrum in the energy range of \(10^{16}{-}3\times 10^{17}\) eV and a feature of this spectrum at about \(10^{17}\) eV are analyzed in detail and are described. The spectrum in question is compared with the results obtained at some other arrays.
