- Abstract
- The a resonant scattering on Ne-18 was measured in inverse kinematics to understand the a-clustering of proton-rich Mg-22 nucleus, performed at the CNS Radio-Isotope Beam Separator (CRIB) of Center for Nuclear Study, University of Tokyo, located at the RIBF of RIKEN Nishina Center. The excitation function of Mg-22 was obtained for the excitation energies of 10-16 MeV by adopting the thick-target method. Several resonances were evident in the present work, which implies the existence of energy levels with large a widths. Since energy levels were not clearly observed at the astrophysically important energy range, upper limits on the Ne-18 (a, a)Ne-18 cross section were set. The astrophysical impact was also investigated by estimating the Ne-18 (a, p)Na-21 cross section.
