Description
Deuterons and ³He represent a few per cent of the cosmic-ray nuclei. They are mainly produced by fragmentation reactions of primary cosmic ⁴He nuclei on the interstellar medium and represent a very sensitive tool to verify and constrain CR propagation models in the galaxy, providing additional information to that of the cosmic B/C ratio. Precision measurements of the deuteron and ³He fluxes obtained with a high-statistics data sample collected by the AMS-02 aboard the International Space Station will be presented.
