Structure and decay pattern of linear-chain states in neutron-rich Carbon isotopes

The linear-chain states of14C are studied by using the antisymmetrized molecular dynamics. The calculated properties of the linear-chain states were compared with the observed data. The results for the π-bond linear-chain states reasonably agree with the observation. It is also shown that the linear-chain states decay to the excited states of10Be. Hence, we regard that this unique decay pattern is a strong evidence of the linear-chain formation.
