Abstract

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.
