Abstract Inclusive and coincident spectra of alpha particles and fission fragments were measured for the232Th+12C (85 MeV) reaction to study the influence of the excitation energy and the angular momentum on the fission of the compound nucleus and to separate different alpha particle emission mechanisms. At backward angles α emission can be accounted for by the evaporation processes. At forward angles the most important contribution is given by the break-up fusion process. Mass distributions for compound nuclei244Cm (E*=58 MeV,ff coincidences), and240Pu (E*=37 MeV,ff α coincidences) were obtained. In the case of240Pu mass distribution has a shape different from those obtained in light ion reactions at the same excitation energy, indicating the strong influence of the entrance channel. The dependence of the mass distribution shape on the α particle energy is also examined.
