Abstract content

We use the GALPROP code and the ACE data to derive the cosmic ray isotopic composition at the sources. The composition is derived for two propagation models, diffusive reacceleration and plain diffusion. We show that the compositions derived assuming different propagation models are different. We also compare the isotopic composition at the sources with the latest solar composition. This may provide a clue to the origin of low energy cosmic rays and their acceleration time scale.
