Investigation of the 4α linear chain state in ¹⁶O

NUCLEAR REACTIONS ¹²C(α, ⁸Be)⁸Be, (α, ¹²C), [¹²C* decaying to ⁸Be+α], E=12.2-20.0 MeV; measured Eα, Iα, α(θ), αα-coin, σ(E, θ) at Notre Dame FN tandem facility. Phase shift analysis of σ(θ) data. ¹⁶O; deduced levels, resonances, J. Comparison with previous experimental results. No evidence found for rigid, 4α-linear chain in ¹⁶O.
