Description
The Alpha Magnetic Spectrometer operating on the International Space Station is a cutting-edge detector that measures 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 Be10/Be9 ratio measures the cosmic ray propagation volume in the Galaxy, and the Li6/Li7 ratio tests the existence of primordial lithium. Current measurements are limited to energies below 2 GeV/n and are affected by large uncertainties. AMS can extend the measurement of the isotopic compositions up to 11 GeV/n. In this contribution, measurements of Lithium, Beryllium, and Boron isotopic fluxes with AMS data will be presented.
