  The differential energy spectrum of cosmic rays from Cherenkov radiation
measurements in EAS in the energy range of 10^15-10^20eV has been compared with
an anomalous diffusion model for the particles in interstellar space having
fractal properties (Lagutin et al, 2001). The close association between
experimental data and calculated "all particle" spectra in form at E(0)
(10^15-10^18)eV is found. In this case, the average mass composition of cosmic
rays calculated by five components does not contradict the average mass
composition from experimental data which was obtained by several of EAS
characteristics in that energy region.
