Unbound states in ¹²C populated by γ-decay of the (J^π, T) = (2⁺, 1) 16.11 MeV state

NUCLEAR REACTIONS ¹¹B(p, γ), E=400 keV; measured Eα, Iα, αα-coin using DSSSDs, Eγ, Iγ; deduced ¹²C excitation energy spectrum, γ-decay partial widths, branching ratio, B(E1), B(M1), resonance at 16.11 MeV from unresolved γ strength, γ-decay to the 10.8 MeV 1^- state; confirmed transitions to 9.64 MeV 3^- and 12.71 1⁺ states, unresolved γ transitions to natural parity states at 10 MeV and 11.5-13 MeV.
