“…in (Palmer, 1982;Valdés-Galicia, 1993). Recently (Kecskeméty et al, 2011) examined the energy spectra of 0.3-100 MeV protons and found, that at the lower energies, the galactic particle spectra are significantly steeper than the J(E) ∼ E one, predicted by analytical approximations, such as the force-field model of modulation. Usoskin et al (2005) provide a long series of a parameter allowing for a quantitative estimate of the average monthly differential energy spectrum of CR near the Earth for long time interval.…”
