The 18F(p,α)15O reaction rate for application to nova γ-ray emission Original Research Article

The 18F(p,α)15O reaction is recognized as one of the most important reaction for nova gamma–ray astronomy as it governs the early ⩽ 511 keV emission. However, its rate remains largely uncertain at nova temperatures due to unknown low–energy resonance strengths. We report here on our lastest results concerning the study of the D(18F,pα)15N reaction, as well as on the determination of the 18F(p,α)15O reaction rate using the R-matrix theory. Remaining uncertainties are discussed.
