Precision measurement of lithium flux in cosmic rays with the Alpha Magnetic Spectrometer on the International Space Station

Abstract : Lithium nuclei in cosmic rays are produced by the spallation of heavier cosmic rays on the interstellar medium. Thus, the abundance of Lithium constitutes a very sensitive observable for the modeling of cosmic rays propagation in the Galaxy. A precision measurement of the Lithium flux with rigidities from 2 GV to 3 TV by AMS, based on 1.6 million events, is presented for the first time. The variation of the flux spectral index with rigidity is also presented
