Description
The 18Ne(α,p)21Na reaction, one of the breakout reactions from hot-CNO cycle, plays a crucial role in understanding the X-ray bursts and the nucleosynthesis in the rp-process. Because this reaction rate is dominated by the energy levels of 22Mg above the α-threshold at 8.14 MeV, studying the 22Mg nuclide may improve our understanding of the X-ray burst. In order to study the level properties in 22Mg nuclide, the 18Ne(α,α)18Ne scattering reaction was measured in inverse kinematics by using radioactive 18Ne beams and 4He gas cell target at the Center for Nuclear Study Radioactive Ion Beam Separator (CRIB) in RIKEN Nishina center. By adopting thick-target method, the energy levels in 22Mg ranging from ~8.5 MeV to 18 MeV were populated. Details of the experiment and the preliminary results will be discussed in this presentation.
