Abstract

In AGB environment, fluorine and sodium abundances are still matter of debate. About ¹⁹F (only stable isotope of fluorine), its abundance in the universe is strictly related to standard and extra-mixing processes taking place inside AGB-stars, that are considered to be the most important sites for its production. Nevertheless the way in which it is destroyed is far from being well understood. On the other hand, ²³Na presence in Globular Clusters, along with is well-known anticorrelation with oxygen has made clear that this element must be produced in previous generations stars, and intermediatemass AGB stars are one of the possible candidates for its production. For this reason we studied the ¹⁹F(α,p)²²Ne and ²³Na(p,α)²⁰Ne reactions in the energy range of relevance for astrophysics via the Trojan Horse Method (THM), using the three-body reactions 6Li(¹⁹F, p²²Ne)d and ²³Na(d, pn)²⁰Ne.
