The O(α, γ) Ne reaction is generally considered as a potential breakout reaction from the hot CNO cycle. Under nova conditions, the reaction rate is dominated by a single sub-Coulomb resonance at E = 504 kev which corresponds to a Ne excitation energy of E = 4.033 MeV. Results from a d(Ne, Ne)p experiment show that states of astrophysical interest are populated in this reaction. An upper limit for the α-branching ratio of the 4.033 MeV state was identified and branching ratios for other states in Ne were found to be in good agreement with stable beam based results.
