The spectra originating from the electric dipole transitions of nd (n=3−5) core excited states to the 5f valence states of Am²⁺ to Am⁸⁺ ions have been calculated using the Dirac-Hartee-Fock method, which are compared with the results from the Flexible Atomic Code for the explanation of accuracy. It is found that both the and spectra of these ions consist of two peaks that are well separated in energy respectively by 202.11 eV and 49.10 eV due to strong spin-orbit interaction of the and hole state, while the spectra show a broad quasi-continuum profile.

5 f态对镅离子的nd → 5 f跃迁能和光谱的影响

使用 Dirac-Hartee-Fock 方法计算了源自nd ( n = 3−5) 个核心激发态到Am ²⁺到 Am ⁸⁺离子的 5 f价态的电偶极子跃迁的光谱，并进行了比较使用灵活原子代码的结果来解释准确性。发现这些离子的和光谱均由两个峰组成，由于空穴态和自旋轨道的强相互作用，这些峰的能量分别为 202.11 eV 和 49.10 eV ，而光谱显示出宽的准连续谱轮廓。
