【 摘 要 】

We discuss new results concerning the investigation of the19F(p,α0)16O and10B(p,α0)7Be reactions at low energies. Both reactions are important for the nuclear spectroscopy of the formed compound nucleus, i.e.20Ne and11C respectively, and play a role in nuclear astrophysics. For the10B(p,α0)7Be case, a comprehensive analysis of our reaction data and other scattering data points out the possible presence of an unreported state in11C at Ex≈ 9.36 MeV. For the19F(p,α0)16O case, the study of the low energy angular distributions testifies the role played by low energy resonances in the S-factor, leading to an enhanced reaction rate at stellar energies.
