The multi-channel random neck-rupture model of Brosa, Grossmann and Mueller has been very successful in the theoretical prediction of fission fragment properties. The experimental distributions of mass and kinetic energy for the spontaneous fission of 252Cf have been analysed in the framework of the Brosa model, taking into account a better representation of the dependence on the total kinetic energy of the fragments. The results of their parametrisation compared to the experimental data are presented. For 238Np the multi-fission channel calculations have been performed using the programs of Brosa. The results are surprising in that there seems to be an overlap of the so-called standard I and standard II fission channels. This will certainly have an influence on the total kinetic energy distributions of the fragments. There is also evidence for a third splitting of the standard channel, standard III. The resulting channel graphs are presented.
