Phys. Rev. Lett. 95, 031101 (2005) [4 pages]Hydrogen Burning of 17O in Classical NovaeSee Also: Erratum Received 22 April 2005; published 14 July 2005 We report on the observation of a previously unknown resonance at ERlab=194.1±0.6 keV in the 17O(p,α)14N reaction, with a measured resonance strength ωγpα=1.6±0.2 meV. We studied in the same experiment the 17O(p,γ)18F reaction by an activation method and the resonance-strength ratio was found to be ωγpα/ωγpγ=470±50. The corresponding excitation energy in the 18F compound nucleus was determined to be 5789.8±0.3 keV by γ-ray measurements using the 14N(α,γ)18F reaction. These new resonance properties have important consequences for 17O nucleosynthesis and γ-ray astronomy of classical novae. © 2005 The American Physical Society URL:
