对于完全相对论的四分量多电子波函数,已经提出了六种电子定域性指标(ELI)。它们的对应物,适用于2分量波函数的应用程序,也已推出。在Ar和Rn原子上测试了六种建议的指标,其中之一,空间反对称电子对的ELI-D,已被发现在定量水平上揭示原子壳层结构。使用该指示剂获得了周期表4-7周期所有原子的壳结构,并与非相对论极限计算以及标量相对论(零级正则近似)计算获得的结果进行了比较。© 2014 Wiley Periodicals,Inc.
For the fully relativistic 4‐component many‐electron wavefunction six flavors of electron localizability indicators (ELI) have been proposed. Their counterparts, suitable for the application to the 2‐component wavefunctions, have been also derived. Six proposed indicators have been tested on Ar and Rn atoms and one of them, the ELI‐D for spatially antisymmetrized electron pairs, has been found to reveal atomic shell structures at quantitative level. Shell structures of all the atoms of periods 4–7 of the periodic table have been obtained using this indicator and compared with these obtained from the nonrelativistic limit calculations as well as from scalar‐relativistic (zero‐order regular approximation) calculations. © 2014 Wiley Periodicals, Inc.
