The creation of carbon and oxygen in our Universe is one of the forefront questions in nuclear astrophysics. The determination of the abundance of these elements is key to our understanding of both the formation of life on Earth and to the life cycle

The 19F(α, p)22Ne reaction is considered to be the main source of fluorine depletion during the Asymptotic Giant Branch phase in stars. The reaction rate still retains large uncertainties due to the lack of experimental studies available. The yields

The shape of the low-energy part of the β-delayed α-particle spectrum of 16N is very sensitive to the α+12C reduced width of the 7.117 MeV subthreshold state of 16O. This state, in turn, dominates the low-energy p-wave capture amplitude of the ast

The low-energy part of the beta alpha -decay spectrum of 16N permits the determination of the reduced alpha -width theta alpha 2 of the 7.12 MeV subthreshold state of 16O, which dominates the low-energy p-wave capture amplitude of the astrophysically

The ${}^{13}C(\ensuremath{\alpha},n){}^{16}O$ reaction constitutes the dominant neutron source for the main $s$ process, which operates at a thermal energy of $\mathit{kT}=8$ keV. Since the cross section at stellar energies is very small, the reactio
