Description

Cosmic rays inside the heliosphere interact with the solar wind and with the interplanetary magnetic field, resulting in a temporal variation of the cosmic ray intensity near Earth for rigidities up to a few tens of GV. Previous AMS results on proton and helium spectra showed that the two fluxes behave differently in time. In this contribution, the precision results of the light ions up to Oxygen for the 12.5 years of data collected by the AMS will be presented including detailed temporal variations of the fluxes.
