Abstract

The Trojan Horse Method has been recently applied to the study of reactions involved in fluorine nucleosynthesis inside AGB stars. Fluorine abundance is important since it allows to constrain mixing models from the comparison of the observed fluorine abundances with the ones predicted by models. Anyway direct measurements of the cross section do not extend down to the Gamow peak, which is the astrophysically relevant energy region. In particular the study focuses on the ¹⁵N(p,α)¹²C and the ¹⁸O(p,α) ¹⁵N reactions which can influence fluorine yield as they are part of ¹⁹F production/destruction network.
