Temporal variation of cosmogenic nuclide production

Typical time spans relevant to cosmic ray exposure dating are at least tens to hundreds of solar cycles therefore the dependence of production rates on the 11-year 

Dunai (2001b) has fitted his scaling parameters Nioso and A to cutoff rigidity instead of inclination in order to enable a full description of cosmic ray flux variations, including non-dipole components  

Cosmogenic nuclide production at depth and on eroding surfaces 

Depth dependence of cosmogenic nuclide production beneath a flat surface. So 

The exponential decrease according to Equation (20) is only valid for the spallation-
