Phys. Rev. Lett. 87, 023001 (2001) [4 pages]Dramatic Structure in the Photodetachment of Inner Shells of Negative Ions: Li-Received 12 March 2001; published 20 June 2001 Deep inner-shell photodetachment of negative ions is shown to differ qualitatively and quantitatively from the corresponding process in neutral atoms and positive ions. As an example, calculations of the photodetachment of Li- out of the 1s shell, using an augmented R-matrix methodology, are presented and show numerous structures over a broad energy region including a new phenomenon: Auger decay of a shape resonance. Li- was selected because it is the simplest multishell negative ion and is amenable to experimental scrutiny. © 2001 The American Physical Society URL:
