| 英文摘要 | The threefold massive fragment in hot nuclei with medium mass number has been measured in Ar-40 + In-115, Rh-103, and Nb-93 reactions at 25MeV/u. The fragments emitted at angles larger than 32 degrees are detected by ten parallel plate position-sensitive avalanche counters (PPAC), each with an area of 25 x 20cm(2). The total kinetic energies (TKE), the yield ratio P-32 of the threefold fragmentation to fission, and the distributions of the fragment mass, velocity, and relative angle, etc., are obtained. From the mass ratio of the fragments, a simple empirical expression is deduced. By analyzing their angular correlation function with a simple space-time model, the time difference between two scission points in the threefold process in the Ar + In reaction system is derived. A systematics of P-32 versus Z(2)/A for hot nuclei is observed. |
