Nonrelativistic energy levels of helium atom
D. T. Aznabaev, A. K. Bekbaev, Vladimir I. Korobov
The nonrelativistic ionization energy levels of a helium atom are calculated for , , and states. The calculations are based on the variational method of "exponential"…

Leading order relativistic corrections to the ro-vibrational spectrum of $\mbox{H}^+_2$ and $\mbox{HD}^+$ molecular ions
D. T. Aznabayev, A. K. Bekbaev, V. I. Korobov
High-precision variational calculations of the operators for the relativistic corrections in the leading order are presented. The ro-vibrational states in the range of the t…
