Non-adiabatic, Relativistic, and Leading-order QED Corrections for Rovibrational Intervals of ${}^4$He${}_2^{+}$ ($X{}^2{\Sigma }_{\mathrm{u}}^{+}$)

Dávid Ferenc, Vladimir I. Korobov, Edit Mátyus

The rovibrational intervals of the ${}^4$He${}_2^{+}$ molecular ion in its $X{}^2{\Sigma }_{\text{u}}^{+}$ ground electronic state are computed by including the non-adiabatic, relativistic, and lead…
