【 摘 要 】

The 3α + n cluster states of13C are discussed on the basis of antisymmetrized molecular dynamics with the constraint on the harmonic oscillator quanta. We predict two different kinds of the cluster states, the hoyle analogue state and the linear-chain state. The former is understood as the 0+2 state (Hoyle state) of12C accompanied by a valence neutron occupying the s-wave. The latter constitute the parity doublet bands of Kπ1/2±owing to its parity asymmetric intrinsic structure.
