4$\alpha$ linear-chain state produced by ${}^9$Be+${}^9$Be collision

Tomoyuki Baba, Yasutaka Taniguchi, Masaaki Kimura

Extreme nuclear deformations provide great insight into the geometric formation of quantum many-body systems. In this work, the $4\alpha +2n$ linear chain is assessed in ${}^{18}$O. We pre…
