Ionization potential and electron affinity of superheavy element 119: relativistic high-order coupled cluster study with QED corrections

A. R. Saetgaraev, L. V. Skripnikov, I. I. Tupitsyn +5

We report a highly accurate \textit{ab initio} study of the ionization potential (IP) and electron affinity (EA) of element 119. Electronic correlation are treated within the relat…

Orbital collapse and dual states of the $5 g$ electrons in superheavy elements

I. I. Tupitsyn, I. M. Savelyev, Y. S. Kozhedub +5

The problem of orbital collapse of the $5 g$ and $6 f$ electrons in atoms of superheavy elements (SHE) is considered. Previously, the presence of the orbital collapse was established…

Calculations of the binding-energy differences for highly-charged Ho and Dy ions

I. M. Savelyev, M. Y. Kaygorodov, Y. S. Kozhedub +2

The binding-energy differences for $^{163} Ho^{q +}$ and $^{163} Dy^{q +}$ ions with ionization degrees $q = 38$ , $39$ , and $40$ are calculated. The calculations are…
