摘要:

本文用Dirac-Coulomb-Breit相对论耦合团簇方法对超重元素Ni(Nh)及其轻同系物In和Tl的电子亲合势和电离势进行了理论计算。In和Tl的计算在不确定性范围内与测量一致。对于Nh,其中实验是未知的,我们预测的电离势为7.569(48)eV和电子亲和势为0.776(30)eV。

英文摘要:

Theoretical calculations based on the Dirac--Coulomb--Breit relativistic coupled cluster method have been carried out for the electron affinities and ionization potentials of the superheavy element nihonium (Nh) and its lighter homologues In and Tl. The In and Tl calculations are in agreement with measurement within uncertainties. For Nh, where experiment is yet unknown, we predict the ionization potential of 7.569(48) eV and electron affinity of 0.776(30) eV.
