Description

The energy spectrum of the primary cosmic rays is obtained by conversion from the truncated muon size spectrum of EAS studied with the GAMMA array. The previously observed dependence of E0 on Nμtr at various zenith angles is used. It is shown that the present spectrum has the same structure ('bump') as the spectrum determined by another independent multi-parametric energy estimation method confirming that the 'bump' structure is not produced by uncertainties in our methods.
