The results are in agreement with the existing experimental data on the Rydberg spectra of this system. In addition, secondary minima are found in the first two excited states (A 2-SIGMA+ and B'2 PI) at internuclear distance of 5.0 bohr, where the two states have charge-transfer character, in agreement with recent experimental findings. The present calculations are not of sufficient accuracy to reproduce the Van der Waals minimum of the ground state.
