Abstract :
We present a comparison of our model treating fission dynamics in conjunction with light-particle ( n,p,α ) evaporation with the available experimental data for the nuclei 126 Ba, 188 Pt and three isotopes of the element Z=110 . The dynamics of the symmetric fission process is described through the solution of a classical Langevin equation for a single collective variable characterizing the nuclear deformation along the fission path. A microscopic approach is used to evaluate the emission rates for prefission light particles. Entrance-channel effects are taken into account by generating an initial spin distribution of the compound nucleus formed by the fusion of two deformed nuclei with different relative orientations.
