Description
We report on the observation of new properties of secondary cosmic rays
Li, Be, and B measured in the rigidity (momentum per unit charge) range
1.9 GV to 3.3 TV with a total of 5.4 ×106 nuclei
collected by AMS during the first five years of operation aboard the
International Space Station. The Li and B fluxes have an identical
rigidity dependence above 7 GV and all three fluxes have an identical
rigidity dependence above 30 GV with the Li /Be flux ratio of 2.0
±0.1 . The three fluxes deviate from a single power law above 200
GV in an identical way. This behavior of secondary cosmic rays has also
been observed in the AMS measurement of primary cosmic rays He, C, and O
but the rigidity dependences of primary cosmic rays and of secondary
cosmic rays are distinctly different. In particular, above 200 GV, the
secondary cosmic rays harden more than the primary cosmic rays.
