论文摘要
我们采用密度依赖性的相对论平均场理论来研究三轴性和配对相互作用如何影响acttinide核的内部裂变屏障。发现三轴性会降低内部裂变障碍，并改善与许多actinides的实验值一致的一致性。但是，对于某些考虑的核，大约1-2 MEV差异仍然是实验值的差异。通过增加BCS配对强度参数，可以使这种差异更小。在这项工作中，我们证明，调整削皮强度有效地重现了实验性内部裂变屏障以及“配对旋转能”和以一致的方式结合能的核，其中三十宫对内部裂变障碍的影响很大。
We employ density-dependent relativistic mean-field theory to study how the triaxiality and pairing interaction affect the inner fission barriers of actinide nuclei. It was found that triaxiality reduced the inner fission barriers and improved agreement with experimental values for many actinides. However, about 1-2 MeV discrepancy to the experimental values still remained for some of the considered nuclei. Such a discrepancy could be made further smaller by increasing the BCS pairing strength parameter. In this work, we demonstrated that adjusting the paring strength was effective to reproduce the experimental inner fission barriers as well as "pairing rotational energy" and binding energy in a consistent manner for nuclei where the effect of the triaxiality on the inner fission barriers was significant.
