  • Abstract: We consider how tilt and divergence of magnetic field lines in solar corona affect distribution functions of interacting and interplanetary protons. It is shown that signatures of magnetic field geometry may be found in anisotropy of secondary high-energy neutrons and γ-rays, in ratio of numbers of interplanetary to interacting protons, in proton energy spectra, in the characteristic decay times of γ-ray and neutron emissions, and in a spatial distribution of the secondary emission sources on solar disc.
