Abstract：
Angular distributions of the fission-fragments were measured for a series of compound nuclei formed in the bombardments of ₁₆₉Tm, ₁₇₅Lu, ₁₈₁Ta, W, Re, Pt, ₁₉₇Au, Pb and ₂₀₉Bi by ₁₂C ions with mica nuclear track detectors and gold surface barrier silicon detector. All the measured angular distributions can be fitted satisfactorily by the theoretical formula based on the statistical saddle point mcxiei. The trend of variation for K₀² with increasing excitation energy E_* was given at various ranges of fissiiity parameter Z²/A in this work.
