V. A. Dzuba, M. S. Safronova, U. I. Safronova

摘要:

将组态相互作用方法与全阶单双耦合团簇技术相结合,计算了超重元素铌、镧和钌的激发能、电离势和静态偶极极化率。Breit和量子电动力学修正也包括在内。超重元素的结果进行了比较,与早期的计算。类似的计算较轻的类似物,镱,镥,铪被用来研究计算的准确性。最后讨论了最终结果的不确定性估计。

英文摘要:

The combination of the configuration interaction method and all-order single-double coupled-cluster technique is used to calculate excitation energies, ionization potentials and static dipole polarizabilities of superheavy elements nobelium, lawrencium and rutherfordium. Breit and quantum electrodynamic corrections are also included. The results for the superheavy elements are compared with earlier calculations where available. Similar calculations for lighter analogs, ytterbium, lutetium, and hafnium are used to study the accuracy of the calculations. The estimated uncertainties of the final results are discussed.
