| Abstract: | The linear-chain states of C-14 are theoretically investigated by using the antisymmetrized molecular dynamics. The calculated excitation energies and the alpha decay widths of the linear-chain states were compared with the observed data reported by recent experiments. The properties of the positive-parity linear-chain states reasonably agree with the observation, which convinces us of the linear-chain formation in the positive-parity states. On the other hand, in the negative-parity states, it is found that the linear-chain configuration does not correspond to a single eigenstate but is mixed with other configurations in the eigenstates and does not form a single rotational band. As a further evidence of the linear-chain formation, we focus on the alpha-decay pattern. It is shown that the linear-chain states decay to the excited states of daughter nucleus Be-10 as well as to the ground state, while other cluster states dominantly decay into the ground state. Hence, we regard that this characteristic decay pattern is a strong signature of linear-chain formation. |
