Abstract

The 18Ne(α,p)21Na reaction plays a crucial role in the (α,p) process, which leads to the rapid proton capture process in X-ray bursts. The reaction rate depends upon properties of 22Mg levels above the α threshold at 8.14 MeV. Despite recent studies of these levels, only the excitation energies are known for most with no constraints on the spins. We have studied the 24Mg(p,t)22Mg reaction at the Oak Ridge National Laboratory (ORNL) Holifield Radioactive Ion Beam Facility (HRIBF), and by measuring the angular distributions of outgoing tritons, we provide the first experimental constraints on the spins of astrophysically- important 18Ne(α,p)21Na resonances. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlikeLicence.
