46 Cosmic rays are not immutable! ■ ■ ■ The composition of CRs records part of their history! Nuclear reactions in space: information about the matter gone through! In addition, secondary nuclei can be radioactive: cosmic-ray clocks! Paris, 9 th June 2008 — IDAPPʼs two days 2008 — E. Parizot (APC / Univ. Paris 7)
Secondary/primary ratios 47 Strong & Moskalenko (2001) ■ NB: use a complete CR transport model, including diffusion, re-acceleration, etc. Paris, 9 th June 2008 — IDAPPʼs two days 2008 — E. Parizot (APC / Univ. Paris 7)
