Theoretical prerequisites for the upcoming generation of precision spectroscopic experiments
D. Solovyev, T. Zalialiutdinov, A. Anikin +1
Modern resonant spectroscopic experiments to measure transition frequencies in atoms have reached a level where a meticulous description of all aspects of the processes under study…
Atomic electron shell excitations in double- decay
M. I. Krivoruchenko, K. S. Tyrin, F. F. Karpeshin
The problem of the transition of electron shells of atoms to excited states in the process of neutrinoless double- decay is investigated. This subject is crucial for modeling th…
Two-Loop Electron Factor Contribution to Lamb Shift in Muonium and Positronium
Michael I. Eides, Valery A. Shelyuto
We calculate hard spin-independent contributions to energy levels in muonium and positronium which are due to radiatively corrected electron factor insertion in two-photon exchange…
Impact of electron shell excitations on the energy spectrum of -electrons in neutrinoless double- decay
M. I. Krivoruchenko, K. S. Tyrin, F. F. Karpeshin
The electron shell of the daughter atoms often appears excited in the double- decays, which causes a change in the energy taken away by -electrons. The average value and vari…
