Abstract

The photoionization of Cl⁺ leading to Cl²⁺ was measured in the photon energy range of 19.5-28.0eV. A spectrum with a photon energy resolution of 15meV normalized to absolute cross-section measurements is presented. The measurements were carried out by merging a Cl⁺ ion beam with a photon beam of highly monochromatic synchrotron radiation at the Advanced Light Source at Lawrence Berkeley National Laboratory. The measured photoionization of Cl⁺ consists of several autoionization resonances surperimposed on the direct photoionization signal. Most of the prominent resonances are assigned to members of Rydberg series originating from the singlet ground state and from metastable triplet levels within the ground-state configuration of Cl⁺. The direct ionization cross section is no larger than 12Mb.
