In the present paper, we simulate fission process of the excited nuclei 217Fr produced in fusion reactions 19F with 198Pt nuclei in the framework of the Langevin equations. We calculate the pre-scission neutron multiplicity for the excited nuclei 217Fr with considering the effects of temperature and projection of spin about the symmetry axis, K. We show that temperature and projection of spin about the symmetry axis affect on the results of pre-scission neutron multiplicity and without considering the effects of temperature and projection of spin; the results of calculations are less than the experimental data. Furthermore, based on fission process simulation and considering the reduced dissipation coefficient as a free parameter we reproduce experimental data on the pre-scission neutron multiplicity for the excited nuclei 217Fr. We also show that the appropriate value of reduced dissipation coefficient for 217Fr is equal to . |
