摘要：

The linear-chain (LC) structure provides significant insights into quantum many-body systems with geometric configurations. In this study, 4?? + 2n LC was assessed in 18O. The excitation energies, moment of inertia, and ??- and 9Be-decay widths of the LC states were predicted using antisymmetrized molecular dynamics. We predict that there are two 4?? LC bands, K?? = 0+ and K?? = 3???, which exhibit different decay properties. We demonstrate that the K?? = 3??? LC states can be verified by the head-on 9Be + 9Be collision experiments because their states exhibited large decay widths in the 9Be + 9Be channel.
