Description

We present accurate measurements of primary cosmic rays Proton, Helium, Carbon, Oxygen, Neon, Magnesium, Silicon, Sulfur, Iron and Nickel as well as measurements of the secondary cosmic rays Lithium, Beryllium, Boron and Fluorine. The unexpected rigidity dependence of the secondary cosmic ray fluxes and their ratios to the primary cosmic rays such as Li/C, Be/C, B/C, Li/O, Be/O, B/O, F/Si are discussed.The data shows that there are only two classes of primary elements and two classes of secondary elements.
