Study of α cluster structure in ²² Mg

The α-cluster structure in the nuclei has been investigated for the perspective of nuclear structure. Contrary to the case of the 4N nuclei with N = Z, the experimental evidences of the clustering structures for the proton-rich systems are still lacking information. In order to study the interesting proton-rich ²²Mg radionuclide, the ¹⁸Ne(α,α)¹⁸Ne elastic scattering will be measured at the Center for Nuclear Study Radioactive Ion Beam Separator of the University of Tokyo. By comparing the experimentally-obtained excitation function with theoretical R-matrix calculations, the resonance parameters of the ¹⁸Ne+α system will be provided in the energy range ∼ 1MeV < Ec.m. < 12.4MeV.
