The Nucleosynthesis of the Light Elements C to Al by Core Collapse Supernovae

We discuss the production sites of the nuclei from C to Al in solar metallicity stars in the range $\rm 13-35~M_\odot$. We will show how, contrarily to corrent believings, the advanced burning phases and the passage of the blast wave play a pivotal role in determing the final yields of quite a few "light" nuclei. We will also show how the relative contributions of the hydrostatic and explosive burnings depend on the initial mass of the star: the smaller the mass the larger the importance of the explosive burnings.
