Indirect study of 19Ne states near the F18+p threshold

The early E⩽511keV gamma-ray emission from novae depends critically on the F18(p,α)O15 reaction. Unfortunately the reaction rate of the F18(p,α)O15 reaction is still largely uncertain due to the unknown strengths of low-lying proton resonances near the F18+p threshold which play an important role in the nova temperature regime. We report here our last results concerning the study of the d(F18,p)F19(α)N15 transfer reaction. We show in particular that these two low-lying resonances cannot be neglected. These results are then used to perform a careful study of the remaining uncertainties associated to the F18(p,α)O15 and F18(p,γ)Ne19 reaction rates.
