英文摘要	The 18Ne(α, p)21Na reaction is thought to be one of the key breakout reaction from the hot CNO cycle to the rp-process in X-ray bursts. We investigated the resonant properties of the compound nucleus 22Mg by measuring the resonant elastic scattering of 21Na+p. An 89 MeV 21Na radioactive beam was produced by CRIB and then bombarded a 93-μm-thick polyethylene target. The 21Na beam intensity was about 2× 105 pps, with a purity of about 70% on the target. The recoiled protons were measured by three sets of ΔE-E telescope respectively. A wide excitation energy range of 5.5-9.2 MeV in 22Mg was scanned with a thick-target method. Some preliminary results are shown. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.
