We discuss new results concerning the investigation of the F-19(p, alpha(0))O-16 and B-10(p, alpha(0))Be-7 reactions at low energies. Both reactions are important for the nuclear spectroscopy of the formed compound nucleus, i.e. Ne-20 and C-11 respectively, and play a role in nuclear astrophysics. For the B-10(p, alpha(0))Be-7 case, a comprehensive analysis of our reaction data and other scattering data points out the possible presence of an unreported state in C-11 at E-x approximate to 9.36 MeV. For the F-19(p, alpha(0))O-16 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.

Abstract
We discuss new results concerning the investigation of the F-19(p, alpha(0))O-16 and B-10(p, alpha(0))Be-7 reactions at low energies. Both reactions are important for the nuclear spectroscopy of the formed compound nucleus, i.e. Ne-20 and C-11 respectively, and play a role in nuclear astrophysics. For the B-10(p, alpha(0))Be-7 case, a comprehensive analysis of our reaction data and other scattering data points out the possible presence of an unreported state in C-11 at E-x approximate to 9.36 MeV. For the F-19(p, alpha(0))O-16 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
