Abstract
We predict the two-electron ionization ladder (TEIL) of , for n=3–9. This special class of resonances can be observed via electron-lithium scattering experiments. In conjunction with our previous work on such doubly excited states, we conclude that the TEIL spectrum as n→∞ is determined essentially by the rigid-rotor correlated motion of the two valence electrons. It appears that no core-induced, quantum-defect concept is necessary to explain the spectrum.
