论文摘要

超重力元素的连续电离电势(IP)和电子亲和力(EAS),$ 111 \ leq Z \ leq 114 $,即使用相关性的fock-fock-copace-cluster-cluster-cluster-cluster cluster-cluster-cluster-cluster-cluster-cluster-cluster-clasterative-clasterative and(s),rg,cn,nh和fl重新验证(FS-CCSDT)。对于大多数考虑的数量,三重振幅的贡献很重要。通过配置交流方法评估BREIT和频率依赖性的BREIT校正。在模型QED操作器方法中考虑了对IP和EAS的量子电子动力学校正。获得的结果在0.10 eV的不确定性之内。

The successive ionization potentials (IPs) and electron affinities (EAs) for superheavy elements with $111 \leq Z \leq 114$, namely, Rg, Cn, Nh, and Fl are reexamined using the relativistic Fock-space coupled-cluster method with nonperturbative single (S), double (D), and triple (T) cluster amplitudes (FS-CCSDT). For the most of considered quantities, the triple-amplitude contributions turn out to be important. The Breit and frequency-dependent Breit corrections are evaluated by means of the configuration-interaction method. The quantum-electrodynamics corrections to the IPs and EAs are taken into account within the model-QED-operator approach. The obtained results are within 0.10 eV uncertainty.
