摘要

Five-dimensional (5D) fission potential energy surfaces (PES) for uranium nuclei are investigated based on the macroscopic-microscopic Lublin-Strasbourg drop model in the three-quadratic-surface parametrization,and the heights of static fission barriers are obtained.Asymmetric and symmetric fission paths are presented on the 5D PES of 236U for different nuclear shapes.The calculated barrier heights,EA and EB,are quite consistent with the experimental data for all even-even nuclei of uranium isotopes,from 230U to 244U.
