Unique Properties of Secondary Cosmic Rays: Results from the AMS

Year: 2026

Type: conference-paper

Abstract: We report the properties of secondary cosmic rays lithium (Li), beryllium (Be), boron (B), fluorine (F) fluxes measured by the Alpha Magnetic Spectrometer (AMS) on the international Space Station from May 19, 2011 to November 11, 2022. All the spectra deviate from a single power law above hundreds GV and exhibit hardening. The secondary cosmic rays harden twice as much as the primary cosmic rays (such as helium, carbon etc). We also found that the Li-Be-B and F belong to two different classes of secondary cosmic rays.
