Two-dimensional Langevin approach to nuclear fission dynamics
Description
A phenomenological model for large-scale nuclear collective motion in the exit channel of fusion-fission reactions on the basis of a two-dimensional Langevin approach is discussed. For the symmetric fission of the 215Fr compound system the influence of the nuclear temperature T and of the two-body viscosity coefficient μ0 on the distribution of the total kinetic energy has been studied. Calculated time scales are compared with reaction times extracted from pre-fission multiplicities of light particles. (orig.)
