Study of 38Ca resonances in the 34Ar($\alpha$,p)37K reaction via proton scattering in 37K

The 34Ar($\alpha$,p)37K reaction is important in Type I X-ray bursts (XRBs), where nucleosynthesis proceeds through the $\alpha$,p and rp processes up to A$<$100. Waiting-point nuclei in XRBs (e.g. 34Ar) are in (p,$\gamma$)-($\gamma$,p) equilibrium and may stall the burst, but the ($\alpha$,p) reaction may provide a detour. We performed 37K+p elastic scattering to study the compound nucleus 38Ca at the ReA3 facility at the National Superconducting Cyclotron Laboratory using a 37K beam incident on a CH$_2$ target. Scattered protons were detected in telescopes of Si strip detectors, while coincident heavy recoils were detected in a gas ionization chamber. Experimental results will be presented and implications for XRB nucleosynthesis and observables discussed.
