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.American Physical Society (APS)2016-10-07engjournal articleVoRhttp://hdl.handle.net/2115/63899https://doi.org/10.1103/PhysRevC.94.0443032469-9985Physical review C944044303https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/63899/1/PhysRevC.94.044303.pdfapplication/pdf1.39 MB2016-10-07
