S - factor of 14 N ( p , γ ) 15 O at astrophysical energies ?
The astrophysical S(E) factor of N(p, γ)O has been measured for effective center-of-mass energies between Eeff = 119 and 367 keV at the LUNA facility using TiN solid targets and Ge detectors. The data are in good agreement with previous and recent work at overlapping energies. R-matrix analysis reveals that due to the complex level structure of O the extrapolated S(0) value is model dependent a...

متن کاملImproved lead and bismuth (n,γ) cross sections and their astrophysical impact
A series of (n,γ) neutron capture measurements on the lead isotopes and bismuth have been carried out at the CERN n TOF installation in the neutron energy range from 1 eV up to 1MeV. At n TOF, contaminations due to scattered neutrons were reduced down to a negligible level by using improved γ-ray detectors with very low neutron sensitivity. The background level has been determined precisely fro...

متن کاملFusion cross sections at deep subbarrier energies
A recent publication reports that heavy-ion fusion cross sections at extreme subbarrier energies show a continuous change of their logarithmic slope with decreasing energy, resulting in a much steeper excitation function compared with theoretical predictions. We show that the energy dependence of this slope is partly due to the asymmetric shape of the Coulomb barrier, that is its deviation from...
