Description
The Alpha Magnetic Spectrometer operating on the International Space Station is a cutting-edge detector that is measuring spectra of cosmic ray particles and nuclei, including the isotopic composition of light nuclei, which is essential to understand cosmic ray propagation and origin. The 10Be/9Be ratio measures the cosmic ray propagation volume in the Galaxy, and the 6Li/7Li ratio tests the existence of primordial lithium. Current measurements are limited to energies below 2 GeV/n and are affected by large uncertainties. AMS is able to extend the measurement of the isotopic compositions up to 11 GeV/n. In this talk, measurements of Lithium, Beryllium and Boron isotopic fluxes with AMS data will be presented.
