Abstract

The α-clusterization of an atomic nucleus has been studied for a long time, even from the earliest days of nuclear physics. Our understanding of the α-cluster structure is, however, mainly limited to the self-conjugate A = 4n (n = 2, 3, 4, · · ·) light nuclei and some of the neutron-rich radionuclides such as 10 Be, 11 B, and 14 C. In order to study the α-cluster structure of a neutron-deficient 22 Mg nucleus, we have measured the 18 Ne(α, α) 18 Ne scattering in inverse kinematics by using radioactive 18 Ne beams and the 4 He gas target at the Center for Nuclear Study radioactive ion beam separator of the University of Tokyo. Recoiling α particles from the scattering were detected by using silicon strip detectors, which constitute ΔE-E telescopes for particle identification. By adopting a thick target method, we were able to investigate a wide range of excitation energies E x = 9.9 - 16.5 MeV in 22 Mg in this work.
