Does anyone know the peak(or the energy at which the flux is the greatest) of the GCR spectrum? And a quotable source for that. I am pretty sure it is in the 1-10 GeV/nucleon range.
thanks

This page says thaty the GCR (Galactic cosmic Ray) spectrum peaks near 300 MeV

Actually that data seems to be the particle count through 1.27 mm of Aluminum. Although I am trying to look up their reference for it. So it appears that I am still trying to find what the actual peak of the GCR is. In Gaisser's book he has a couple of plots but I am trying to verify them to myself since they are slightly misleading I think.
So if anyone can offer some more help I would appreciate it.
Cheers

How about Stecker, or the references he cites?
