Nuclear recoil effect on the binding energies in highly charged He-like ions

A. V. Malyshev, R. V. Popov, V. M. Shabaev +1

The most precise to-date evaluation of the nuclear recoil effect on the $n=1$ and $n=2$ energy levels of He-like ions is presented in the range $Z=12-100$. The one-electron recoil…
