Relativistic recoil corrections of order \boldmath: Hydrogen-like atom and hydrogen molecular ion

Vladimir I Korobov

The finite operators are derived for the recoil order relativistic corrections (to spin-averaged energy levels) in hydrogen-like atoms and ions in the two- and three-bo…

Polarizability of the kaonic helium atom

D. T. Aznabayev, A. K. Bekbaev, V. I. Korobov

The static dipole polarizability of metastable states in the kaonic helium atoms is studied. We use the complex coordinate rotation method to properly account for the resonant natu…

Calculation of the nonrelativistic Bethe logarithm in the velocity gauge

V. I. Korobov

We consider a general procedure to evaluate the Bethe logarithm for a general few-body atomic or molecular system. As benchmarks we use calculation for the ground states of a heliu…
