Abstract：
294MeV Ne Beam has bombarded Tb target.The energy spectra of emitted α particles have been measured at the angles of 10°—150° using ΔE-E telescopes and analyzed by means of three moving source models.The parameters associated with fast source,intermediate source and fusion evaporation source have been obtained.The shape,the peak value and the magnitude of the experimental spectrum have been reproduced by theoretical calculations.Moreover,the angular distribution of α particle has been also fitted very well.The experimental cross section of emitted α particles is 3300mb and the correspondent theoretical value by moving source model is 3700mb.
