我们利用时变 Hartree-Fock 框架内的 Skyrme 有效核相互作用来评估包含 Skyrme 相互作用的张量项对 16 O– 16 O 反应聚变窗口的影响。我们发现，势垒周围的较低融合阈值对这些力的细节相当不敏感，但较高的阈值（高于该阈值，原子核相互穿过）在不同的张量参数化之间会发生几 MeV 的变化。结果表明，最终聚变特性可能成为有效核相互作用评估或拟合过程的一部分
We make use of the Skyrme e ff ective nuclear interaction within the time-dependent Hartree-Fock framework to assess the e ff ect of inclusion of the tensor terms of the Skyrme interaction on the fusion window of the 16 O– 16 O reaction. We find that the lower fusion threshold, around the barrier, is quite insensitive to these details of the force, but the higher threshold, above which the nuclei pass through each other, changes by several MeV between di ff erent tensor parametrisations. The results suggest that eventually fusion properties may become part of the evaluation or fitting process for e ff ective nuclear interactions
