  • Abstract: This paper is desinged to bring to the attention the fact that the effect of focusing of solar energetic particles is always essential as compared with scattering, no matter how small value of the mean free path may be. That is why, an ordinary ('focusing free') diffusion approach can not be applied to the solar cosmic ray transport. In the case of high-energy solar particles, the focused diffusion is demonstrated to lead to a power law decay of energetic particle intensity much like an ordinary diffusion. However, the power law index of the decay is 'renormalized' by the focusing.
