First Direct Measurement of the $^{17}$F($p,\gamma$)$^{18}$Ne Cross Section*

The rate of the $^{17}$F($p,\gamma$)$^{18}$Ne reaction is of significant importance in astrophysical events like novae and x-ray bursts. A $3^{+}$ state in $^{18}$Ne predicted to dominate the rate was found at 599.8 keV using the $^{17}$F($p,p$)$^{17}$F reaction [1], but the resonance strength was unknown. For the first time, the $^{17}$F($p,\gamma$)$^{18}$Ne reaction has been measured directly with the Daresbury Recoil Separator, using a mixed beam of radioactive $^{17}$F and stable $^{17}$O from the HRIBF at ORNL. Resonant proton capture cross sections, $\gamma$ widths, and resonance strengths for the 599.8 keV and 1178 keV resonances will be reported, as well as an upper limit on the direct capture cross section at an intermediate energy.
