The Ce-132 compound nucleus was formed in fusion reactions Ni-64 + Zn-68 and O-16 + Sn-116 at different excitation energies. High energy gamma-rays have been measured in coincidence with Evaporation Residues (ER) in these reactions. At the same time Light Charged Particles (LCP) were measured with the same gate on ER for all the reactions in order to verify and compare the amount of pre-equilibrium emission using mass-symmetric and mass-asymmetric entrance channels. Results on alpha-particle spectra will be presented together with a moving source fit analysis.
