Abstract：
Mica track detectors were used for the measurement of evaporation residues and fission fragments of compound nuclei formed in ¹²C+ ²⁷Al, ¹²C+ ²⁰⁹Bi and ¹⁴N+Pb reactions. The complete fusion cross-sections and excitation functions were then obtained. By using the sharp cut-off model approximation, the values of the critical angular momenta were extracted from the complete fusion cross-sections. The results obtained were compared with the calculations based on current theories for critical angular momentum; they were found to agree within experimental uncertainties.
