An analysis is made of the masses and spectral features for cosmic rays
in the PeV region, insofar as they have a bearing on the problem of the
interaction of cosmic ray particles.
In our Single Source Model we identified two 'peaks' seen in a summary
of the world's data on primary spectra, and claimed that they are
probably due to oxygen and iron nuclei from a local, recent supernova.
In the present work we examine other possible mass assignments. We
conclude that of the other possibilities only Helium and Oxygen (
instead of 0 and Fe) has much chance of success; the original
suggestion is still preferred, however. Concerning our location with
respect to the SNR shell, the analysis suggests that we are close to it

  • probably just inside.
