| 英文摘要 | Emission orders of light charged particles and Li fragments from highly excited fissioning nuclei in the reaction of Ar-40 + Au-197 at E-beam/A = 25 MeV have been studied by measuring difference velocity distributions of two correlated particles at small relative angles in coincidence with two fission fragments. By comparing the data with three-body trajectory calculations, it is found that high-velocity light particles (tritons and He particles) are emitted prior to high-velocity Li fragments but low-velocity light particles are emitted after low-velocity Li fragments. On the other hand, no preferential emission was observed among light particles, such as deuterons and tritons. |
