First Direct Measurement of the {sup 17}F(p,{gamma}){sup 18}Ne Cross Section

Description/Abstract

The rate of the {sup 17}F(p,{gamma}){sup 18}Ne reaction is important in various astrophysical events. A previous {sup 17}F(p,p){sup 17}F measurement identified a 3{sup +} state providing the strongest resonance contribution, but the resonance strength was unknown. We have directly measured the {sup 17}F(p,{gamma}){sup 18}Ne reaction using a mixed beam of {sup 17}F and {sup 17}O at ORNL. The resonance strength for the 3{sup +} resonance in {sup 18}Ne was found to be {omega}{gamma}=33{+-}14(stat){+-}17(syst) meV, corresponding to a {gamma} width of {gamma}{sub {gamma}}=56{+-}24(stat){+-}30(syst) meV. An upper limit on the direct capture of S(E){<=}65 keV b was determined at an energy of 800 keV.
