It has been shown that galactic interaction and mergers can give rise to large-scale tidal shocks that propagate through their gas. As a result, this can give rise to a new population of cosmic rays, additional to standard galactic cosmic rays present in star-forming galaxies. We investigate the impact of this tidal cosmic-ray population on the nucleosynthesis of lithium in interacting systems in the context of the cosmological lithium problem. Moreover we also demonstrate that the development of these interaction shock-waves and may also have far reaching consequences on our understanding of galactic evolution and star formation history, by affecting the far-infrared radio correlation observed in star-forming galaxies.
