High energy cosmic ray spectroscopy. III. Further analyses

In recent papers (A.D. Erlykin and A.W. Wolfendale, Astropart. Phys. 7 (1997) 1, 203) we presented evidence favouring the identification of "structure" in the size spectrum of cosmic ray electrons and muons with heavy nuclei originating in a single local, recent, supernova. Inevitably, such a claim, in a field that is notoriously difficult, has not met with universal agreement. In the present work we add more recent evidence and address the criticisms. Almost all of the evidence considered appears to support our claim; the remainder is neutral. (C) 1998 Elsevier Science B.V.
