主　　题：fragments multiplicity secondary decay 

摘      要：The multiplicity of fragments in Fermi energy heavy-ion collisions was experimen- tally extracted. Compared with the results of calculation using the antisymmetrized molecular dynamics （AMD） model which accounts for the primary fragments only, the results calculated using the AMD together with a statistical decay code GEMINI to account for the deexcitation of excited primary fragments are in better agreement with those extracted from the experiment. This observation indicates that the experimental multiplicity distribution may be significantly different from those of primary fragments.
