Quantum shell effects drive many aspects of many-body quantal systems and their interactions. Among these are the quasifission reactions that impede the formation of a compound nucleus in superheavy element (SHE) searches. Fragment production in quasifission is influenced by shell effects as a nontrivial manifestation of microscopic dynamics hindering the full equilibration of the composite system to form the compound nucleus. In this Letter, we use the microscopic time-dependent Hartree-Fock (TDHF) theory to study ⁴⁸Ca+²⁴⁹Bk collisions to investigate the influence of the tensor component of the effective nucleon-nucleon interaction. The results show that the inclusion of the tensor force causes the spherical shell effect to become more prominent, particularly for the neutron number yield whose peak is exactly at magic number $N=126$. This suggests that the tensor force plays a compelling role in the evolution of dynamical shell effects in nuclear reactions, influencing the competition between spherical and deformed shell gaps.

量子壳层效应推动了多体量子系统及其相互作用的许多方面。其中包括在超重元素 (SHE) 搜索中阻碍复合核形成的准裂变反应。准分裂中的碎片产生受壳效应的影响，这是微观动力学的一种重要表现，阻碍了复合系统完全平衡以形成复合核。在这封信中，我们使用微观时间相关的 Hartree-Fock (TDHF) 理论来研究⁴⁸ Ca+ ²⁴⁹Bk 碰撞研究有效核子-核子相互作用的张量分量的影响。结果表明，张量力的加入使球壳效应更加突出，尤其是峰值恰好在幻数处的中子数产额$ñ=126$. 这表明张量力在核反应中动态壳层效应的演变中起着重要作用，影响了球形和变形壳层间隙之间的竞争。
