Laird, A.M., Cherubini, S., Ostrowski, A.N. et al. (18 more authors) (2002) Indirect study of the astrophysically important 15O(alpha,gamma)19Ne reaction through 2H(18Ne,19Ne)1H. Physical Review C, 66 (4). Art. No. 048801. ISSN 1089-490X
The 15O(α,γ)19Ne 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 Ec.m.=504 keV which corresponds to a 19Ne excitation energy of ER=4.033 MeV. Results from a d(18Ne,19Ne)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 19Ne were found to be in good agreement with stable beam based results.
