T. H. Dinh, V. A. Dzuba, V. V. Flambaum

摘要:

本文对超重元素Z=112的能级进行了精确的从头计算。将相对论Hartree-Fock方法和组态相互作用方法与多体微扰理论相结合,构造了价电子的多电子波函数,并包含了核价关联。两种不同的方法,其中元素被视为一个系统,两个或十二个外部电子以上的封闭壳层被使用和比较。汞的类似计算用于控制计算的准确性。并将计算结果与其它计算结果进行了比较。

英文摘要:

Accurate ab initio calculations of the energy levels of the superheavy elements Z=112 are presented. Relativistic Hartree-Fock and configuration interaction methods are combined with the many-body perturbation theory to construct the many-electron wave function for valence electrons and to include core-valence correlations. Two different approaches in which the element is treated as a system with two or twelve external electrons above closed shells are used and compared. Similar calculations for mercury are used to control the accuracy of the calculations. The results are compared with other calculations.
