组态相互作用+全级原子计算方法的发展

Development of a configuration-interaction + all-order method for atomic calculations

M. S. Safronova, M. G. Kozlov, W. R. Johnson, Dansha Jiang

摘要:

本文在相对论多体理论的框架内发展了一种理论方法来精确地处理价电子较少的原子中的关联修正。该方法结合了目前用于精确计算单价原子性质的全阶方法和适用于多电子体系的构型相互作用方法。该方法适用于镁,钙,锶,锌,镉,钡和汞,以评估电离能和低的能级。

英文摘要:

We develop a theoretical method within the framework of relativistic many-body theory to accurately treat correlation corrections in atoms with few valence electrons. This method combines the all-order approach currently used in precision calculations of properties of monovalent atoms with the configuration-interaction approach that is applicable for many-electron systems. The method is applied to Mg, Ca, Sr, Zn, Cd, Ba, and Hg to evaluate ionization energies and low-lying energy levels.
