Ro-vibrational states of H⁺₂. Variational calculations

The non-relativistic variational calculation of a complete set of ro-vibrational states in the H+2 molecular ion supported by the ground 1sσ adiabatic potential is presented. It includes both bound states and resonances located above the n = 1 threshold. In the latter case we also evaluate a predissociation width of a state wherever it is significant. Relativistic and radiative corrections are discussed and effective adiabatic potentials of these corrections are included as supplementary files.
