Abstract：
The inclusive α-particles ade measured with different kinds of telescopes.The energy spectra,angular distribution,the contour plot of d ²σ/dEdΩ in the E-Θ plane and of d ²σ/PCdEdΩ in velocity plane are obtained.The α-particles coming from the evaporation of compound nucleus are distinguished from the ones of direct mechanism.With a calculation of Exciton of Exciton Model,the contributions from the preequilibrium and equilibrium α-emission are determined respectively.A small contribution comes from other reaction mechanisms.
