AbstractAbstract
[en] The dynamics of statistical fluctuations at fission are discussed. Quadratic and non-quadratic potentials are considered and the Fokker-Planck equation is solved for a one-dimensional model. As an example the fission of 205At is discussed. (BRB)

AbstractAbstract
[en] A Fokker PLanck equation is used for the problem of nuclear fission. The decay rate is computed within a three dimensional calculation and the influence of coupling terms in the transport coefficient tensors is considered. Initial conditions at the saddle point for the collective degrees of freedom are dynamically obtained in the stationary situation. Finally, dynamics of fluctuations from saddle to scission is treated under the same assumptions on the propagation

AbstractAbstract
[en] An explanation for the experimentally observed linear momentum transfer in light and heavy-ion induced reactions is propounded by simple geometrical considerations in momentum space. We display explicitly the transition from one-body to two-body dissipation. We obtain a surprising agreement with the experiments over the whole measured energy range

AbstractAbstract
[en] We calculate the fission-fragment kinetic-energy distribution for the compound nucleus 213At by simultaneously taking into account spreading in a stretching degree of freedom and fluctuations in a fission degree of freedom. This is done in terms of an approximate solution of a two-dimensional Fokker-Planck equation obtained by propagating Gaussian bundles in momentum space. When compared as functions of nuclear temperature with experimental data, our calculated mean kinetic energies are in approximate agreement and our calculated variances are slightly too small
