We observed single and double proton emissions in the O14+He4 interaction by the thick target inverse kinematic (TTIK) method at initial energy for O14 at 32.7 MeV. We found that the protons mainly originate from the resonance excitation of states in Ne18. The observed states in Ne18 decay by protons mainly to proton unstable states in F17. It was found that the decay of a state in Ne18 at Eex=8.45 MeV demonstrates the features of a decay by a correlated proton pair. The observed properties of the O14+He4 interaction make a previous interpretation for the rate of O14(He4, p)F17 at astrophysical energies suspect. We show how the TTIK method should be modified to obtain the data of astrophysical interest. 2007 The American Physical Society.
