摘要

【正】 The fragment angular distributions of fusion-fission reactions for the systemsof ¹⁶O+²³²Th,¹⁹F+²³²Th and ¹⁶O+²³⁸U at near-and sub-barrier energies were measured.The measured fragment anisotropies obviously deviate from the predictions ofscission-point transition-state model.We also compared the excitation energy of tiltingmode with the statistical assumption.It was found that thermal equilibrium is not estab-lished at scission for the reactions studied.
