Energy and lifetime of one-electron multicharged-ion states in front of an Al surface

The energy and width of one-electron multicharged-ion states interacting with an Al surface are determined using the nonperturbative coupled angular mode method. The case of the He⁺, Li²⁺, and O⁷⁺ states is studied. The various states within the n manifolds mix to form hybrids with very different energies and widths. The hybridization within the manifolds can be analyzed in terms of Stark mixing. {} 1996 The American Physical Society.
