相对论平均场计算（纯哈特里计算）在再现某些赝自旋二重态（轨道为n$，l$，j=l+1/2$和n\ensuremath{-}1$，l+2$，j=l+3/2$）的单粒子能量时存在问题，并可能导致不正确的幻数。作者展示了如何在相对论性Hartree-Fock计算中纠正这一点。特别是，$\ensuremath{\rho}$-张量耦合起着重要的作用。这些结果为处理动态核介质中吸引力和排斥力之间的微妙平衡提供了定性的指导。
Relativistic mean-field calculations (pure Hartree calculations) have problems reproducing the single-particle energies for some pseudo-spin doublets (orbits with $n$, $l$, $j=l+1/2$ and $n\ensuremath{-}1$, $l+2$, $j=l+3/2$) and can lead to incorrect magic numbers. The authors show how this can be corrected in a relativistic Hartree-Fock calculation. In particular, the $\ensuremath{\rho}$-tensor coupling plays an important role. The results provide qualitative guidance for treating the delicate balance between attractive and repulsive interactions in the dynamic nuclear medium.
