用Fock空间本征值独立的相对论耦合团簇计算核电离势

Relativistic coupled-cluster calculation of core ionization potential using the Fock space eigenvalue independent partitioning technique

Chiranjib Sur, Rajat K. Chaudhuri

摘要:

在本文中,我们已经应用了集团展开分析的波算子Ω,它结合了轨道弛豫和相关效应,在一个有效的方式。我们用普通有序团簇算符(Ω)和正规有序团簇算符(Ω)计算了Ne、Ar和Kr不同态的电离势。我们的计算结果清楚地显示了弛豫和关联效应在确定电离势中的作用,这是理论光谱学中有趣的方面之一。

英文摘要:

In this paper we have applied the cluster-expansion ansatz for the wave operator Ωwhich incorporates the orbital relaxation and correlation effects in an efficient manner. We have used both ordinary and normal ordered cluster operator (Ω) to compute the ionization potential for different states of Ne, Ar, and Kr. The result in our calculation clearly shows how the relaxation and correlation effects play the role in determining the ionization potential, one of the interesting aspects in theoretical spectroscopy.
