Abstract: 
Photoionization experiments were performed with tungsten ions using a photon-ion merged-beams setup at the Advanced Light Source. Cross-sections sigma(q,q+1) for photon-induced single ionization of Wq+ ions (q = 1, 2, 3, 5) and sigma(q,q+2) for photon-induced double ionization of W+ ions have been explored in the energy range 20-70 eV. While sigma(q,q+1) for the lower charge states is dominated by broad resonance features in the range of 4f and 5p excitations, the cross-section sigma(5,6) shows much narrower peak features. Significant contributions from initial metastable states are evident. Double ionization is substantially enhanced at energies above the threshold for single ionization of a 4f electron in W+.
