The 19F(p, α1,2) reaction studied via Trojan Horse Method in astrophysical range of interest.

The complex reaction network connected to the ¹⁹F stellar abundance is very sensitive to the physical condition in stars. To overcome difficulties present in the direct measurements, mainly the very low cross section in the astrophysical energy range due to the Coulomb repulsion, an indirect measurement of the ¹⁹F(p, α) reaction, with the Trojan Horse Method (THM), was performed at INFN-LNS. While the method had been successfully used to study α₀ channel, in the present analysis focus was given to the α_1,2 channels, where better knowledge of the reaction rates at low energies is required, obtainable by employing the THM method.
