Description
A long-standing puzzle in cosmic ray physics has been the nature
of the spectrum, which is very well modeled by a broken power law
with differing exponents, both close to -3, above and below the "knee".
We show that a rather simple hadronic evaporation model reproduces
the correct exponents, and the location of the knee without free
parameters. The model is predictive, with some successful predictions
already and has broader implications for nuclear physics and particle
astrophysics.
