Abstract
Context. Direct observation of ¿-ray emission from the decay of 18F ejected in classical nova outbursts remains a major focus of the nuclear astrophysics community. However, modeling the abundance of ejected 18F, and thus the predicted detectability distance of a ¿-ray signal near 511 keV emitted from these transient thermonuclear episodes, is hampered by significant uncertainties in our knowledge of the key 18F(p, a) reaction rate. Aims. We analyze uncertainties in the most recent nuclear phy...
