Single and multiple photoionization of Wq+ tungsten ions in charge states q=1,2,..,5: experiment and theory

[摘要] Absolute cross sections for single and multiple photoionization of Wq+ions have been measured in a photon-ion merged beam setup employing synchrotron radiation from the Advanced Light Source. The experimental data are compared to large-scale close-coupling calculations within the Dirac-Coulomb R-matrix (DARC) approximation.
