Search for evidence of rotational cluster bands in ¹⁸O

NUCLEAR REACTIONS ¹²C(⁷Li, p)¹⁸O^*, E=44.0 MeV; measured reaction products, recoil protons, (¹⁸O break-up particle)α-coin using the Q3D magnetic spectrograph, and the Birmingham large-angular-coverage DSSD array at the Maier-Leibnitz Laboratory (MLL) in Garching. ¹⁸O; deduced levels, J, π, total widths, Γ_α/Γ branching ratios, barrier penetration, θ_α², bands, no evidence of consistent (¹⁴C+α or ¹²C+2n+α) cluster structure for any of the bands. Comparison with previous experimental results.
