The fusion of neutron-rich ²⁰O on ¹²C at energies in the range of 20 MeV ≤ E_lab ≤ 41 MeV was measured at the GANIL accelerator facility located in Caen, France. The design, principles of operation, and calibration of the detectors used to perform the measurement are described. Analysis of coincident evaporation residues and light charged particles produced in the decay of the compound nucleus, ³²Si*, has been performed. The fusion cross-section associated with the de-excitation of the compound nucleus leading to the emission of charged particles has been determined and compared with predictions of a simple fusion model. For reference, the fusion of ¹⁶O + ¹²C has been measured in the energy range of 20 MeV ≤ E_lab ≤ 42 MeV and the fusion cross-section for the charged particle decay channels extracted. The ¹⁶O fusion cross-section has also been compared with statistical model calculations in order to demonstrate the ability of the model to predict the formation and de-excitation of the compound nucleus for β-stable nuclei.
