Description
A precision measurement of the antiproton to proton ratio in the primary cosmic rays in the rigidity range from 1 to 450 GV based on 350,000 antiproton events collected by the Alpha Magnetic Spectrometer on the International Space Station will be presented. The antiproton-to-proton flux ratio reaches a maximum at ∼20 GV and is rigidity independent above 60.3 GV.
