介绍了一种实验研究材料基态自旋轨道分裂态相对布居的方法。该方法利用X射线吸收光谱中的多重态结构，选择规则限制了在给定的最终状态配置中可以达到的项的子集。这个子集依赖于基态的精确细节。介绍了这种方法在Ce材料上的试验。结果是一致的，在基态的4f 72/1到4f 52/1的贡献的比例增加，增加4f能级和导电状态之间的杂交。
The authors introduce a method to investigate experimentally the relative populations of spin-orbit-split states in the ground state of a material. The method uses multiplet structure in X-ray absorption spectra and selection rules limit the subset of terms that can be reached in a given final-state configuration. This subset is dependent on the precise details of the ground state. A test of this method on Ce materials is presented. The results are consistent with an increase in the ratio of 4f72/1 to 4f52/1 contributions in the ground state with increasing hybridization between the 4f levels and the conduction states.
