我们回顾了超核的各个方面的相对论平均场方法。布罗克曼和韦泽首先将这种方法应用于超核。当时，实验上已经观察到超核的自旋轨道分裂比普通核小得多。由于自旋轨道相互作用是在相对论框架下自然产生的，因此相对论方法适合于讨论超核中的自旋轨道分裂。自从这项开创性的工作以来，已经取得了许多进展，相对论方法已经应用于超核的基态和激发态。我们将在本章中总结这些发展。我们将集中讨论$\Lambda$-超核，而不讨论$\Sigma$超核，因为理论上的处理彼此相当相似。
We review the relativistic mean-field approach to various aspects of hypernuclei. It was Brockmann and Weise who first applied this approach to hypernuclei. At that time, it had been already observed experimentally that the spin-orbit splittings in hypernuclei are significantly smaller than that in ordinary nuclei. The relativistic approach was suitable for a discussion of spin-orbit splittings in hypernuclei, as the spin-orbit interaction is naturally emerged with the relativistic framework. Since this seminal work, many developments have been done and the relativistic approach has been applied both to the ground state and to excited states of hypernuclei. We summarize those developments in the Chapter. We shall concentrate on $\Lambda$-hypernuclei and do not discuss $\Sigma$ hypernuclei, since the theoretical treatment is rather similar to each other.
