Scientific paper

We consider diffusive propagation of galactic cosmic rays with energies up to 10 exp 17 eV. It is shown that drift (Hall diffusion) of particles in the global regular magnetic field of the Galaxy may be responsible for the observed 'knee' in the cosmic ray energy spectrum at 3 x 10 exp 15 eV. The model implies weak energy dependence of cosmic ray diffusion along the magnetic field lines, D proportional to E, m = 0.15-0.20, for a unique power law in the entire energy range 10 exp 9 - 10 exp 17 eV.
