The 0.987MeV resonance in the 14N(p,gamma)15O reaction.

The 14N(p,gamma)15O reaction is the bottleneck of the hydrogen burning CNO cycle. Recent studies of this reaction at E < 500 keV have led to a revision of the S-factor value. However, also data at higher energy are necessary to predict the extrapolated S-factor at energies of astrophysical interest. Here we report on a new study of the E = 0.987MeV (Ex = 8.284MeV) resonance carried out at the high-current FZD Tandetron in Dresden. Solid TiN targets and four escape-suppressed HPGe detectors have been used.
