Some questions of origin and interaction of cosmic rays of very high and ultrahigh energies
A new approach to description of the energy spectrum of cosmic rays without the well-known specific features—the knee (at 3 × 1015 eV) and ankle (at 5 × 1018 eV)—is considered. These features are explained as a result of the change in the character of particle interaction in the range of very high and ultrahigh energies.
