Abstract
TAKING the confinement mechanism for cosmic rays in the Galaxy to be resonant scattering by Alfvén or hydromagnetic waves generated by the streaming of the cosmic rays themselves1,2, I shall show that the abundant low energy cosmic rays can generate, indirectly, enough Alfvén waves of long wavelength to scatter cosmic rays of considerably higher energy. Cosmic rays of energy up to around 1,000 GeV may thus be confined within the Galaxy more efficiently than has previously been supposed.
