Abstract

The transport equation for cosmic rays in the Galaxy is solved simultaneously with equation for energy density of magnetohydrodynamic turbulence. The obtained spectra of cosmic ray nuclei with energies 105 to 1011 eV are consistent with observational data, including the peak in the ratio of secondary to primary nuclei fluxes at around 1 GeV/nucleon.
