TL;DR
This paper investigates the significant impact of intershell correlations on heavy atoms, showing that partial contributions deviate from electron counts, highlighting the importance of intershell interactions.
Contribution
It introduces a detailed analysis of intershell correlations in heavy atoms within the RPA with exchange, emphasizing their strong effects.
Findings
Partial contributions deviate from electron counts in subshells.
Intershell interactions have a strong influence on atomic properties.
The RPA with exchange preserves the dipole sum rule.
Abstract
We demonstrate that in the frame of the random phase approximation with the exchange, which preserves the validity of the precise well known dipole sum rule, the partial contributions for given subshells strongly deviates from the number of electrons in these subshells. This demonstrates strong effects of intershell interaction in atoms.
