Abstract
It is suggested that the spectrum of galactic cosmic rays with energie s greater than or similar to 10(15) eV is formed in the surroundings o f pulsars. Acceleration of particles with energies greater than or sim ilar to 10(15) eV occurs at the expense of their interaction with the electric field of the pulsar wind. The maximum attainable energy of th e accelerated particles is determined by the potential difference betw een the polar and equatorial regions of the pulsar, and can be as high as 10(19) - 10(20) eV.
