Study of atomic effects on electron spectrum in bound-muon decay process
M. Y. Kaygorodov, Y. S. Kozhedub, A. V. Malyshev +3
For the bound-muon decay process, the study of atomic effects on the electron spectrum near its endpoint is performed within the framework of the Fermi effective theory. The analys…
QED calculations of intra--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 states from the ground state as well as the $2s2p \, ^3P_1 \rightarrow 2s2p…
