Bound and Continuum Properties of Lathanide and Actinide Anions and Atoms

轻电离介质到高z原子的理论研究很少，因为它们需要同时包含相对论和相关性。对于后者，开放的d和/或f亚壳层电子的存在使得获得准确的计算结果非常具有挑战性。这些元素占元素周期表的一半以上，在催化、先进照明光源、原子钟、核废料、半导体缺陷、稀土磁铁、高温超导体、氢储能、等离子体聚变装置、天体物理学等领域具有重要的技术意义。负离子对理论家和实验者来说都是特别具有挑战性的。该研究将继续对上述束缚态系统进行计算，并将工作扩展到处理连续体特性，如光电离和共振的能量和宽度。

Lightly ionized medium to high-Z atoms have been little studied theoretically, because they require the simultaneous inclusion of relativity and correlation. For the latter, the presence of open d and/or f subshell electrons makes obtaining accurate computational results quite challenging. These species, which constitute over half the periodic table, are technologically important in catalysis, advanced lighting sources, atomic clocks, nuclear waste, semi-conductor defects, rare-earth magnets, high temperature superconductors, hydrogen energy storage, plasma fusion devices, astrophysics, etc. The negative ions are particularly challenging to both the theorist and experimenter.The research will continue calculations on the aforementioned bound state systems and extend the work to treat continuum properties such as photoionization and the energies and widths of resonances.
