The existence of linear-chain configurations in light nuclei has been predicted for decades, but the finding of the exact ___location on the nuclear chart where this exotic structure emerges has proven to be challenging experimentally. Here, the authors performed an inelastic excitation and cluster-decay experiment followed by unambiguous spin-parity analyses and provide evidence for the emergence of the nuclear chain structure starting from 14C.
