Abstract
Based on the Weizsäcker-Skyrme (WS4) mass model, the fission barriers of nuclei are systematically studied. Considering the shell corrections, macroscopic deformation energy, and a phenomenological residual correction, the fission barrier heights for nuclei with can be well described, with an rms deviation of 0.481 MeV with respect to 71 empirical barrier heights. In addition to the shell correction at the ground state, the shell correction at the saddle point and its relative value are also important for both deformed and spherical nuclei. The fission barriers for nuclei far from the -stability line and super-heavy nuclei are also predicted with the proposed approach.魏茨泽克-斯基姆质量模型的裂变势垒*
基于魏茨泽克-斯基姆（WS4）质量模型，系统地研究了原子核的裂变势垒。考虑到壳校正、宏观形变能和现象残差校正，可以很好地描述原子核的裂变势垒高度，与 71 个经验势垒高度的均方根偏差为 0.481 MeV。除了基态的壳校正，鞍点的壳校正及其相对值对于变形核和球核也很重要。所提出的方法还预测了远离稳定线的原子核和超重原子核的裂变势垒。
