Scientific paper

Attention is given to the problem of explaining the shape of the spectrum of very energetic cosmic rays, particularly those above 10 to the 19th eV where evidence for a flattening of the spectrum is becoming stronger. It is proposed that the particles above 10 to the 19th eV are mainly extragalactic and that they originate from heavy nuclei generated in clusters of galaxies which are largely trapped but from which fragmentation neutrons are able to escape and decay to protons outside the region of confining fields.
