Extreme nuclear deformations provide great insight into the geometric formation of quantum many-body systems. In this work, the 4α+2n linear chain is assessed in 18O. We predict excitation energies, moment-of-inertia, α-, and 9Be-decay widths by using the antisymmetrized molecular dynamics. We show that the Kπ=3− linear-chain states may be verified by the head-on 9Be+9Be collision experiments.
