“…Present work assignment for a peak at this energy based on a DWBA angular distribution analysis of the 20 Ne(p, d) reaction [16,46]. In contrast, Laird et al in their low-energy study of the 19 F( 3 He, t) reaction [22] comment that the state is not "low spin".…”

s-wave resonances for the 18F(p,$\alpha$α)15O reaction in novae

The 18 F(p, α) reaction determines the rate of destruction of 18 F in novae. It represents the key nuclear physics uncertainty in modelling the calculated flux of annihilation radiation emitted following the radioactive decay of 18 F. The major uncertainties relate to states representing s-wave resonances in the compound system, 19 Ne. We report a first study of the 19 F(3 He, t) 19 Ne reaction at intermediate energies and forward angles. This reaction has a simple, model-independent, mechanism that we use here to identify states near the proton threshold energy in 19 Ne corresponding to ΔL = 0 transitions. In particular, we observe a ΔL = 0 state at 6.13 MeV which could significantly affect the 18 F(p, α) astrophysical S-factor at nova burning temperatures.

Application of the THM to the investigation of reactions induced by unstable nuclei: the¹⁸F(p,α)¹⁵O case

et al. 2019

The Trojan Horse Method is applied to the investigation of the 18F(p,α)15O reaction, by extracting the quasi free contribution to the 2H(18F,α15O)n process. For the first time the method is applied to a reaction of astrophysical importance involving a radioactive nucleus. After investigating the reaction mechanism populating the a + 15O + n exit channel, we could extract the 18F(p,α)15O cross section and calculate the astrophysical factor over the 0 – 1 MeV energy interval. The possibility of exploring the cross section with no need of extrapolation allowed us to to point out the possible occurrence of a 7/2+ state at 126 keV, which would strongly influence the trend of the astrophysical factor at the energies of astrophysical interest. However, the low energy resolution prevents us to draw definite conclusions. Possible astrophysical consequences are also discussed, motivating further work on this reaction.
