对原子 Ni 的 2p-3d 共振光吸收光谱和 2p 光电子能谱进行了实验和理论研究。光谱分析考虑到，在金属蒸发温度约为 1800 K 时，3d(8) 4s(2) 和 3d(9) 4s 两种构型的精细结构状态 3d(8) 4s(2) 3F 和 3d(9) 4s 3D 均已填充。这两种构型的总体提供了与凝聚相（Ni金属和NiO）中相应光谱进行比较的独特可能性，其中当前构型相互作用计算使用构型的混合（3d，4s）（10）。通过使用我们对 2p 光电离的理论描述，我们发现了对这些凝聚相光谱的新见解。
The photoabsorption spectrum of the 2p-3d resonances and the 2p photoelectron spectrum of atomic Ni were investigated both experimentally and theoretically. The analysis of the spectra takes into account that at the evaporation temperature of the metal at about 1800 K the fine structure states 3d(8) 4s(2) 3F and 3d(9) 4s 3D of both configurations 3d(8) 4s(2) and 3d(9) 4s are populated. The population of these two configurations offers the unique possibility for a comparison with the corresponding spectra in the condensed phase (Ni metal and NiO) where current configuration interaction calculations use the mixture of the configurations (3d,4s)(10). By using our theoretical description of the 2p photoionization new insight into these condensed phase spectra is found.
