Trajectories of high-energy cosmic rays in the galactic disk

Abstract
Trajectories of high-energy cosmic ray particles, the rigidity of which corresponds to protons of energy E0 = 1018 eV, have been calculated numerically, using a quasi-longitudinal model of the magnetic field in the galactic disk. In this way an idea of cosmic radiation transfer at extremely high energies is obtained under specified assumptions concerning the magnetic field in the galactic disk. The galactic or extragalactic origin of particles reaching the Earth, as well as the angular distribution of such particles, is discussed. The possibility of particle transfer from the galactic centre to the Earth is investigated.
