解释Breit效应的广义RECPs：铀、钚和超重元素112、113、114
Generalized RECPs accounting for Breit effects: uranium, plutonium and superheavy elements 112, 113, 114
摘要：
本文介绍了广义相对论有效实势（GRECP）方法，它能以经济的方式和高精度地模拟Breit相互作用和有限核模型。生成了铀、钚、类汞（E112）、类铊（E113）和类铅（E114）原子的相应GRECP。这些GRECPs和其他群体的RECPs的准确性估计在原子数值SCF计算与库仑两电子相互作用和点核相比，相应的全电子Hartree-Fock-Dirac-Breit计算与费米核电荷分布。用全电子四分量方法研究了不同核模型和不同壳层间Breit相互作用的贡献。
英文摘要：
The Generalized Relativistic Effective Core Potential (GRECP) method is described which allows one to simulate Breit interaction and finite nuclear models by an economic way and with high accuracy. The corresponding GRECPs for the uranium, plutonium, eka-mercury (E112), eka-thallium (E113) and eka-lead (E114) atoms are generated. The accuracy of these GRECPs and of the RECPs of other groups is estimated in atomic numerical SCF calculations with Coulomb two-electron interactions and point nucleus as compared to the corresponding all-electron Hartree-Fock-Dirac-Breit calculations with the Fermi nuclear charge distribution. Different nuclear models and contributions of the Breit interaction between different shells are studied employing all-electron four-component methods.
