摘要：

The F-18(p, alpha)O-15 reaction is the predominant destruction mechanism in novae of the radionuclide F-18, a target of gamma-ray observatories. Thus, its rate is important for understanding F-18 production in novae. We have studied resonances in the F-18 + p system by making a measurement of a proton-transfer reaction F-18(d, n). We have observed 15 Ne-19 levels, 5 of which are below the proton threshold, including a subthreshold state, which has significant l(p) = 0 strength. Our data provide a direct determination of the spectroscopic strength of these states and new constraints on their spins and parities, thereby resolving a controversy, which involves the 8- and 38-keV resonances. The F-18(p, alpha)O-15 reaction rate is reevaluated, which takes the subthreshold resonance and other new information determined in this experiment into account.
