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