Abstract：
Nuclear shapes in fission process have been described by using a generalized Cassinian ovals.The calculated fission barriers and effective moments of inertia of saddle-point configurations are in good agreement with the experimental data.The calculated fission barriers for a wide range of nuclei as a function of angular momentum are close to the prelicted values by the CPS Model based on describing nuclear shapes in terms of a spherical harmonic expansion with lowest nine even order terms.
