The 18O(a,y)22Ne reaction is part of a reaction chain that produces the 22Ne(a,n) neutron source for the slow neutron-capture process. However, the astrophysically relevant resonances in the 18O(a,y)22Ne reaction are difficult to measure due to their small resonance strengths. An experiment optimized for background suppression and detection efficiency was recently performed to measure the resonance strengths of these low-energy resonances. The experiment was performed at the Sanford Underground Research Facility (SURF), in the 4850-foot underground cavern dedicated to the Compact Accelerator System for Performing Astrophysical Research (CASPAR). The experimental end station used the -summing High Efficiency Total Absorption Spectrometer (HECTOR). Preliminary results from this experiment will be presented.
