Abstract：
The Langevin equation including particle emission was used to reproduce the recently measured spin distribution of evaporation residue cross sections in the reaction ¹⁶O+¹⁸⁴W at beam energies of 84, 92, 100, 108, 116 and 120MeV. By comparing the theoretical calculations with the experimental data, the validity of the stochastic approach to dissipative fission is verified. Moreover, a pre-saddle nuclear viscosity coefficient of 5×10²¹s^－1 is extracted.
