Abstract：
The fragment angular distributios for ¹⁶O+ ¹⁵⁹Tb, ¹⁶O+ ¹⁹⁷Au and ¹⁶O+ ²⁰⁹Bi reactions have been measured by the solid state track detctors. After subtraction of the contribution of intermediate mass fragment (IMF), the fission angular distributions have been fitted by the transitional state statistical model (TSM) and the single spin standard theory to extract the spins of the fission nuclei. The relation between spinsand bombarding energies is discussed.
