Abstract
We have measured, by time-of-flight techniques, the charge-state distr ibutions of ions of argon and potassium following X-ray absorption at energies near their respective K-edges. We confirm previously observed enhancements of the higher charge states at energies up to 100 eV bel ow the K-edge in argon. The measurements confirm recent calculations s uggesting excitation of a virtual Is state in this energy range.
