Abstract:
Deformation consisting of a series of quasi-Cassinian rotating bodies surrounding a inner joined sphere is assumed to be that associated with symmetric multifold fissions into two or more fragments. The deformation shapes with only one parameter evolve smoothly from that of an initial spherical nucleus to the scission point. The shapes are calculated using a quasi-Cassinian ovaloid shape parameterization, which has been demonstrated to be a good approximation for binary fission.Using this parameterization the deformation potential and barriers in 2,3,4,6 and 8-fold multifold fissions are calculated. Proximity effects are included. The temperature dependence of these fission barriers is considered too. Finally the fission dynamics delay effects on the multi-fission processes is also discussed.
