| 英文摘要 | Fragment-fragment correlation functions have been measured in E/A = 30 MeV Ar-40 + Ag-nat reaction via the technique of intensity interferometry. Emission times of intermediate mass fragments have been extracted from reduced velocity correlation functions by using the threebody trajectory model. The average emission time of intermediate mass fragments varies with the energy of fragments. It decreases from about 300fm/c for low energy fragments to about 80 fm/c for energetic fragments. After subtracting the contribution of projectile-like fragments, average emission times of mid-rapidity fragments are of the order of 250 fm/c for this reaction. It indicates that intermediate mass fragments emitted in this reaction mainly come from sequential binary decays. |
