Abstract：
The fission cross sections and the evaporation residue cross sections for ¹²C+ ²⁰⁹Bi and ¹⁴N+Pb reactions were measured with the gold surface barrier silicon detectors and the mica nuclear track detectors.The critical angular momentum l _erwas deduced from the measured evaporation residue cross section σ _eron the basis of the sharp-off model.The fission barrier with the particular angular momentum i derived from the condition Γ _f/Γ _n=1 at l=l _eThe angular momentum effect of the fission barrier was studied experimentally.
