QED calculations of intra- $L$ -shell singly excited states in Be-like ions

A. V. Malyshev, Y. S. Kozhedub, V. M. Shabaev +1

The \textit{ab initio} approach is used to evaluate the excitation energies of the $2 s 2 p^{2 S + 1} P_{J}$ states from the ground state as well as the $2s2p \, ^3P_1 \rightarrow 2s2p…

Convergence-acceleration approach to partial-wave expansion of two-electron self-energy contributions to the Lamb shift

A. V. Malyshev, E. A. Prokhorchuk, V. M. Shabaev

Methods of bound-state QED that treat the self-energy contributions to the Lamb shift within the partial-wave expansion usually face the problem of slow convergence of the latter.…

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…
