Estimating primary mass composition at energies 10 super(17)-10 super(18) eV from EAS radio emission lateral distribution

Distribution of maximum depths of extensive air showers (EAS) with energies of 10 super(17)-10 super(18) eV is restored from the lateral distribution of EAS radio emission measured by the LOPES experiment (40-80 MHz). Dependence of the EAS maximum depth on its energy is constructed and mass composit...

Zusammenfassung:Distribution of maximum depths of extensive air showers (EAS) with energies of 10 super(17)-10 super(18) eV is restored from the lateral distribution of EAS radio emission measured by the LOPES experiment (40-80 MHz). Dependence of the EAS maximum depth on its energy is constructed and mass composition of cosmic rays is estimated. It follows from the obtained dependencies that the fraction of light cosmic ray's nuclei increases in the energy range under consideration.
