Abstract: 8Be_gs coincidences with ¹²C, ⁸Be_gs and α-particles produced in the ¹²C + ¹²C interaction at 65 MeV have been measured in a wide in-plane angular range. The 3-⁸Be_gs final state is found to be produced, even if poor statistics prevent any identification of the ¹⁶O states involved in the first stage of the process. The ⁸Be_gs - α and ⁸Be_gs - ¹²C coincidence yields are found to be to ¹²C and ¹⁶O excited states, decaying into the ⁸Be_gs + α and ¹²C + α system, respectively.
