Abstract

We present of measurements of radio emission from EAS at the frequency 32 MHz performed in 2008-2012. Showers were selected by zenith and azimuth directions, sampled by energy. A mean lateral distribution function was fitted to the data each interval. The paper presents unied approximation formula for all three energy intervals of lateral distribution, using connection between equation (1) and (2) coefficients with energy and geomagnetic angle. Here we analyze the connection between the shape of lateral distribution and the depth of the maximum shower development Xmax too.

The depth of maximum shower development and its fluctuations: cosmic ray mass composition at E_0 >= 10^17 eV

A. Sabourov, S. Knurenko (2010)

We present new data on Cherenkov light observations obtained during the period 1994-2009, after a modernization of the Yakutsk EAS array. A complex analysis of \(\xmax\) and its fluctuations \(\sigma(\xmax)\) was performed over a wide energy range. With the new data, according to QGSJet II model, an estimation was made of the cosmic ray mass composition for \(\E \sim 10^{17} - 3 \times 10^{19}\) eV. The result points towards a mixed composition with a large portion of heavy nuclei at \(\E \sim 10^{17}\) eV and the dominance of light nuclei at \(\E \sim 10^{19}\) eV. The analysis of \(\sigma(\xmax)\) energy dependence for the same energies qualitatively confirms this result. The shape of the \(\xmax\) distribution at fixed energy \(10^{18}\) eV is analysed to make more precise conclusions on cosmic ray mass composition.
