Title: Absolute single photoionization cross-section measurements of Rb 2+ ions: experiment and theory

Abstract

Absolute single photoionization cross-section measurements of Rb 2+ ions were performed at the Advanced Light Source at Lawrence Berkeley National Laboratory using synchrotron radiation and the photo-ion, merged-beams technique. Measurements were made at a photon energy resolution of 13.5 2.5 meV from 37.31 to 44.08 eV spanning the 2 P ground state and 2 P metastable state ionization thresholds. Multiple autoionizing resonance series arising from each initial state are identified using quantum defect theory. The measurements are compared to Breit-Pauli R-matrix calculations with excellent agreement between theory and experiment.
