Abstract
The energy and width of the state of are calculated using Feshbach projection operators and the Stieltjes moment method. The results are compared with an analysis of the double minima in the potential-energy curves of the Rydberg states. The doubly excited configuration is unstable with respect to autoionization for , and the autoionization rate is sensitive to both the value of the internuclear separation and the energy of the emitted electron.
