Abstract：
Light particle emission at around 107°and 128°in the reaction induced by 25MeV/u ⁶He from ⁹Be target were clearly observed. The shape of the energy spectra obtained is consistent with an equilibrium evaporation from a source with a temperature of 5.6MeV or 5.2MeV for complete fusion or for incomplete fusion, respectively. A large number of tritons were detected compared to the number of protons, which may be related to the widely studied exotic cluster structure and the isospin effect of ⁶He.
