The THM has been applied to the study of reactions involved in the fluorine production in AGB stars with the aim of extending these measurements down to the Gamow peak. 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. In particular the study focuses on the {sup 15}N(p,{alpha}){sup 12}C and the {sup 18}O(p,{alpha}){sup 15}N reactions which can influence fluorine yield as they are part of {sup 19}F production (and destruction) network.
