Charged-particle decays of highly excited states in 19F
Abstract
Neutron-capture reactions on 18F in the helium-burning shell play an important role in the production of 15N during core-collapse supernovae. The competition between the 18F(n,p/α)18O/15N reactions controls the amount of 15N produced. The strengths of these reactions depend on the decay branching ratios of states in 19F above the neutron threshold. We report on an experiment investigating the decay branching ratios of these states in order to better constrain the strengths of the reactions.
