Abstract:

Cluster structure of low-lying T = 0 states in 20Ne is investigated by “16O - α) + (^12C-^8Be)'' coupled channel orthogonality condition model, with focusing on the rotational aspect of this nucleus. The following six rotational bands are treated by taking account of the cluster structure with ``^16O + α''- and ``^12C + ^8Be''-like characters and the shell-model-like structure describable by the exact treatment of the antisymmetrization in the present model space; K^π = 0_1^+, 0_2^+, 0_3^+, 0_4^+, 2^- and 0^- bands built on 0_1^+(g.s.), 0_2^+(6.72 MeV), 0_3^+(7.19 MeV), 0_4^+(∼8.3 MeV), 2^-(4.97 MeV) and 1^-(5.78 MeV) states, respectively. Level energies are calculated and compared with the observed onew. The analysis of the wave functions shows that the viewpoint of the cluster structure is indispensable to understand the essential characters of these rotational bands comprehensively.
