Description

A description of the technique and results of the search for showers produced by neutral particles, such as high-energy gamma rays and astroneutrino, is presented. In order to do that, a comprehensive analysis of the data of electrons, muons and Cherenkov light of EAS and their time responses in scintillation and Cherenkov detectors was carried out. The upper limit of the flux of gamma quants at energies 3*10^18 eV, 10^19 eV, and 3*10^19 eV was obtained. Multiparametric analysis of the characteristics of showers did not reveal the EAS formed by the neutrino.
