22Ne excess in cosmic rays from the inner galaxy

The abundances of heavy cosmic ray nuclei at the solar system are calculated in a 3 dimension galactic model with cylindrical symmetry and with diffusive confinement. In this model the overabundance of 22Ne is energy dependent. A comparison with HEAO data is suggestive of a radial dependent source of 22Ne in the galaxy steeper than the source of the other heavy cosmic rays.
