Characterization of the proposed 4-α cluster state candidate in ¹⁶O

NUCLEAR REACTIONS ¹⁶O(α, α'), E=200 MeV; measured Eα, Iα, E(p), I(p), (particle)(particle)-coin, angular correlations of charged-particle decays from ¹⁶O via α and proton decays using K600 magnetic spectrometer at iThemba LABS. ¹⁶O; deduced levels, resonances, L-transfers, J, π, total widths and branching ratios for particle decays of resonances extracted from R-matrix fits, a resonance at 15.090 MeV, 0+ suggested as a candidate for the 4α cluster state, consistent with several theoretical cluster calculations.
