Structure and decay pattern of linear-chain state in 14C
Abstract
The linear-chain states of C are theoretically investigated by using the antisymmetrized molecular dynamics. The calculated excitation energies and the decay widths of the linear-chain states were compared with the observed data reported by the recent experiments. The properties of the positive-parity linear-chain states reasonably agree with the observation, that 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 is fragmented into many states and do not form a single rotational band. As a further evidence of the linear-chain formation, we focus on the decay pattern. It is shown that the linear-chain states decay to the excited states of daughter nucleus 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 the linear-chain formation.
