Abstract
In the framework of dynamical model and considering Langevin equations have been studied the evolution of the excited nuclei produced in fusion reaction 18O+192Os. The average multiplicity of pre-scission neutrons and fission probability have been calculated for the nuclei produced in the reaction 18O+192Os with considering viscosity of the nuclear matter as a free parameter. According to reproduction of experimental data on the pre-scission neutron multiplicity and fission probability has been extracted information about the magnitude of viscosity during transition to the saddle point and scission point. It was shown that for reproducing of the experimental data on the pre-scission neutron multiplicity and fission probability, it is necessary the magnitude of viscosity of nuclear matter increases with increasing excitation energy of the compound nuclei. Furthermore, the variation of viscosity as a function of excitation energy was determined for the nuclei produced in the reaction 18O+192Os during transition to the saddle point and scission point.
