    Abstract:
    'We report the properties of sodium (Na) cosmic rays in the rigidity range 2.15 GV to 3.0 TV with 0.46 million nuclei collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. We observed that above 6 GV the Na flux is well described by the weighted sum of the silicon flux (primary cosmic rays) and the fluorine flux (secondary cosmic rays).rn The fraction of primary component increases with rigidity and becomes dominant at highest rigidities. Na/Si abundance ratio at the source is determined independent of cosmic ray propagation models.'
