Description
For a long time the three main components of extensive air showers have been measured at
the Yakutsk array: the whole charged component, muons with e_{th} \ge 1 GeV and Cherenkov
light. Using these data we reconstruct energy of primary cosmic particle (with
quasi-colorimetric method), estimate the depth of shower maximum (by the shape of charged
particles lateral distribution and a pulse shape of Cherenkov light response in
differential detector, t_{1/2} ) and measure relative muon content at different core
distances. In this work we consider a relation s_{mu} /s_{ch} between charged and muon
components in showers and its fluctuations at fixed energies. The goal of this analysis
is to make a comparison between experimental and computational data for different
primaries and to obtain an estimation of cosmic rays mass composition in the ultra-high
energy domain.
