Abstract：
The characteristics of electromagnetic and hadronic components in high energy cosmic rays at mountain altitude are studied by analysing single-shower events observed by mountain emulsion chamber. The chemical composition of primary cosmic rays in the energy region around 10¹⁴eV is studied by using Monte-Carlo simulation. The simulated power indices of energy spectra and attenuation lengths in air in agreement with the experimental data. The analysis of their vertical intensities indicates that the chemical composition of primary cosmic rays at energies around 10¹⁴eV is not contradicted to the simple extrapolation from lower energies and the abundance of protons can not be less than 30% and that of the nuclei with A≥2 not larger than 70%.
