Spectral characteristics of large-scale cosmic ray fluctuations from data of neutron and ionizing components and their relation to cosmic ray anisotropy.

Spectra describing the intensities of the cosmic ray fluctuations for a low-frequency range from data of neutron and ionizing components of cosmic radiation on the Earth are calculated. Variants are estimated theoretically for reconstructing spectra prior to disturbances of the interplanetary medium and for quiet periods under various values of anisotropy. It is shown that both the anisotropy and the crossing by the Earth of recurrent high-velocity fluxes have to be considered when studying fluctuation phenomena in cosmic rays and their relation to processes in the interplanetary medium.
