Paper Abstract

The study of cosmic rays (CR) of ultrahigh energies first of all requires an estimate of the energy, the spectrum in terms of energies, masses, and the anisotropy of the arrival of primary particles. This can only be done by calculating the energies of all the secondary particles formed during the interaction of the primary particle with the nuclei of the air atoms [1]. First of all, this is the registration of Cherenkov and ionization radiation [2, 3]. According to model calculations, the loss of ionization of air by particles is spent up to ~80% of the total energy of the primary particle [4]. The rest of the energy is spent on nuclear interactions of hadrons (nucleons) and is carried away by high-energy muons at sea level. In the hybrid registration of air showers, i.e. electron, muon, and Cherenkov components, we can empirically estimate the energy of the primary CR particle. Such a method has been developed and is being used to this day at the Yakutsk complex installation of the EAS. A detailed description of this method is given in [5, 6]. As an alternative to the energy balance method, we describe below the method of independent estimation of E0 obtained by measuring the radio emission of EAS at the frequency of 30-35 MHz at the Yakutsk array.
