Abstract：
The fragment angular distributions for 35.9, 41.0, 45.6, and 50.0 MeV/u ¹⁶O+ ¹⁹⁷Au, 50 MeV/u ¹⁶O+ ¹⁵⁹Tb, and 50 MeV/u ¹⁶O+ ²⁰⁹Bi reactions have been measured by the solid state nuclear track detectors. After subtraction of the contribution of intermediate mass fragment (IMF), the fission angular distributions have been fitted by the transition state statistical model (TSM) and the single-spin standard theory to extract the spins of the fissioning nuclei. The relation between spins and bombarding energies is also discussed.
