Abstract

Direct measurements of ${Ar}^{+}$ $1 s^{- 1} 2 p^{- 1} n l$ double-core-hole shake-up states are reported using conventional single-channel photoemission, offering a new and relatively easy means to study such species. The high-quality results yield accurate energies and lifetimes of the double-core-hole states. Their photoemission spectrum also can be likened to $1 s$ absorption of an exotic argon ion with a $2 p$ core vacancy, providing new information about the spectroscopy of both this unusual ionic state as well as the neutral atom.
