Supernovae and 19Ne

18F is a relatively long-lived product in supernovae (> 100 min) so it is very important in astrophysics for monitoring the conditions in the supernova remnants. One reaction which removes 18F from the system is proton capture [18F(p, γ)] which goes through several resonances in 19Ne. In a recent study, it was found that there were some resonances below the proton separation energy, but the spin of one of the states remains uncertain. For complete reaction rate calculations, the spin needs to be measured. By doing 20Ne(p,d) we should be able to determine the spin of this state.
