Galactic cosmic rays are particles with very large spectra. The main applications related to these cosmic rays are dating techniques based on cosmogenic nuclides (e.g. 14C) produced when cosmic rays interact with astrophysical objects (e.g. meteoroids, moons, atmospheres). The most important effects are induced by cosmic rays (proton and helium mostly) with energies between a few tens of MeV up to 15-20 GeV. The study of cosmogenic nuclides requires nuclear codes capable to properly describe this energy range, which can be considered as a low-energy particle physics or a high-energy nuclear physics.
The seminar will discuss two nuclear codes developed to predict the production rate of cosmogenic particles and nuclides in objects exposed to cosmic rays, namely, the Liège Intra-Nuclear Cascade (INCL) model and the CosmicTransmutation model.
