摘要
Inclusive Intermediate-Mass Fragments（IMFs）are measured at seven angles for the<sup>40</sup>Ar+Ag reaction at 25 MeV/u.The energy spectra of IMF from Li to F are obtained.A thermal mod-el with the same parameters well fits the energy spectra of all IMFs at backward angles.These IMFs areevaporated from hot nuclei formed in an incomplete fusion process.The angular distribution and Z distri-bution are calculated with the statistical code GEMINI.
