Description

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
