%X On the basis of the extensive air shower (EAS) data obtained by the GAMMA experiment, the energy spectra and elemental composition of the primary cosmic rays are derived in the 1 - 100 PeV energy range. The reconstruction of the primary energy spectra is carried out using an EAS inverse approach with the hypothesis of power-law primary energy spectra with rigidity-dependent knees. The rigidity- dependent knee feature of the primary energy spectra is displayed at the rigidities ER similar or equal to 2.5 +/- 0.2 PeV/Z and ER similar or equal to 3.1 - 4.2 PeV/Z for the SIBYLL and QGSJET interaction models respectively.;Using the event-by-event method of the primary energy evaluation from the measured N-ch, N-mu and shower age (s) parameters, the all-particle energy spectrum is also obtained.
