Shower accompaniment of hadrons with an energy more than 5 TeV and the primary proton spectrum

The data on shower accompaniment of hadrons in the atmosphere with an energy above 5 TeV are presented. The experiments were carried out at Tien Shan complex system. Energy spectra of αJ/dEh hadrons at different E0/Eh values from the region E0/Eh ≤ 4, where Eh-hadron energy and E0-energy of the hadron, are presented. dJ/dEh spectra have the power from AEγ+1, 1+γ=3.0±0.05 value being uniform for all E0/Eh. The 1+γ=2.68±0.05 value is obtained for primry proton spectrum index from dJ/dEh spectra in the assumption of scaling behaviour with the energy of inclusive cross sections of secondary particles in fragmentation region
