Fluorine Destruction in Stellar Environments
Abundance of 19F exceeds by far the predicted one. This problem represents one of the unanswered questions of stellar modelling. A source of large uncertainties at relevant energies are the 19F(p, α)16O and 19F(α, p)22Ne reactions. Although the lowest energy point from direct experiments are at about ∼660 keV, the astrophysical relevant energy region is only known by R-Matrix calculations. In this work we apply the Trojan Horse Method (THM) to the appropriate quasi-free three-body reactions. The THM application allowed us to study the sub-Coulomb energy region and to get the corresponding S(E)-factor values, thus allowing for a detailed evaluation of its astrophysical impact.
