We report the implementation of the complete set of the lowest-order relativistic corrections of the order of
2 where is the fine structure constant for calculating vibrational states of diatomic molecular systems
within ...

The Darwin and mass-velocity relativistic corrections have been calculated for all pure vibrational
states of the H2 using the perturbation theory and very accurate variational wave functions obtained
without assuming ...

Variational calculations employing explicitly correlated Gaussian functions have been performed for the
ground states of 9Be and 9Be+ including the nuclear motion i.e., without assuming the Born-Oppenheimer
BO ...

Very accurate quantum mechanical calculations of the first five vibrational states of the 4He3He+ molecular
ion are reported. The calculations have been performed explicitly including the coupling of the electronic ...

In this work the authors present an approach to calculate the leading-order relativistic corrections for
ground and excited states of helium isotopomers. In the calculations they used variational wave
functions expanded ...

We have performed high-accuracy quantum mechanical calculations for the three lowest S states of the
beryllium ion 9Be+ . The nonrelativistic part of the calculations was done with the variational approach and
explicitly ...
