Charged-particle decays of highly excited states in ${}^{19}$F

Abstract

Neutron-capture reactions on ${}^{18}$F in the helium-burning shell play an important role in the production of ${}^{15}$N during core-collapse supernovae. The competition between the ${}^{18}$F($n,p/\alpha$)${}^{18}$O/${}^{15}$N reactions controls the amount of ${}^{15}$N produced. The strengths of these reactions depend on the decay branching ratios of states in ${}^{19}$F 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.
