DOIAbstract
18 pages, 8 figures. Accepted in Nuclear Physics AThe early E $\leq$ 511 keV gamma-ray emission from novae depends critically on the $^{18}$F(p,$\alpha$)$^{15}$O reaction. Unfortunately the reaction rate of the $^{18}$F(p,$\alpha$)$^{15}$O reaction is still largely uncertain due to the unknown strengths of low-lying proton resonances near the $^{18}$F+p threshold which play an important role in the nova temperature regime. We report here our last results concerning the study of the d($^{18}$F,p)$^{19}$F($\alpha$)$^{15}$N 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 $^{18}$F(p,$\alpha$)$...
