Abstract

A measurement of the inelastic component of the key astrophysical resonance in the O-14(alpha, p)F-17 reaction for burning and breakout from hot carbon-nitrogen-oxygen (CNO) cycles is reported. The inelastic component is found to be comparable to the ground-state branch and will enhance the O-14(alpha, p)F-17 reaction rate. The current results for the reaction rate confirm that the O-14(alpha, p)F-17 reaction is unlikely to contribute substantially to burning and breakout from the CNO cycles under novae conditions. The reaction can, however, contribute strongly to the breakout from the hot CNO cycles under the more extreme conditions found in x-ray bursters.
