Abstract

Lateral distribution functions of particles in extensive air showers with the energy 
 eV recorded by ground-based and underground scintillation detectors with a threshold of @GeV at the Yakutsk array during the continuous observations from 1986 to 2016 have been analyzed using events with zenith angles θ ≤ 60°. Experimental functions have been compared to the predictions obtained with the QGSJet-01-d hadron interaction model by applying the CORSIKA code. The entire dataset indicates that cosmic rays consist predominantly of protons.
