Study of States Near E$_x=6$ MeV in $^{18}$Ne Using $^{17}$F(p,p)

ORAL

Abstract

The $^{14}$O($\alpha$,p)$^{17}$F reaction rate has a strong influence on the light curve of Type I X-ray bursts. At temperatures lower than 1 GK, this rate is dominated by states in $^{18}$Ne with $E_x\sim6$ MeV. The RESOLUT radioactive-ion beam facility at FSU was used to study $^{18}$Ne resonances around $E_x\sim6$ MeV using $^{17}$F$+p$ scattering in inverse kinematics. We report a combined R-matrix analysis of data from our experiment with data from an earlier study\footnote{J. Hu et al., Phys.Rev.C \textbf{85} 025803(2014)} of the same reaction that covered a broader energy range but with poorer resolution. We will report constraints that can be placed on the spin-parity of resonances and proton partial widths that are important for the $^{14}$O($\alpha$,p)$^{17}$F reaction rate. Results will be compared to information from other reaction studies in the literature.
