The experiment involving the reaction (α +12 C) → (16O∗ + γ) → (α +12 Cg.s.) was performed at the University of Birmingham MC40 cyclotron facility at a beam energy of 12.29±0.04 MeV to study the gamma to alpha emission ratio of a suspected clustered state in 16O at 16.272 MeV , J = 6+. Finding a reduced transition probability value of B(E2; 6+ → 4 +) = 3.316 ± 1.736w.u. = 7.942 ± 4.158 e2 fm4.
This work also presents a method to create simulations of alpha-gamma coincidences with realistic detectors response, which is used to decompose and analyse the components of the detected gamma spectrum to extract the reduced transition probability. The methods described in this work can be employed to study nuclear structure properties by gamma emission of other light nuclei
