Measurement of low-energy resonances in the <sup>22</sup>Ne(α,n)<sup>25</sup>Mg Reaction
ORAL
Abstract
The 22Ne(α,n)25Mg reaction is a key neutron source for the slow neutron-capture process. The reaction rate at stellar energies is most likely dominated by a resonance at 832 keV. Due to low resonance strengths at lower energies only upper limits have been previously determined for resonances below 832 keV. Recent measurements were completed for the strengths of resonances at 832 keV and below. These measurements utilized the Compact Accelerator System for Performing Astrophysical Research (CASPAR), located on the 4850-feet level of the Sanford Underground Research Facility (SURF).
