Description

Single-ionization cross sections for W4+, W5+, and W6+ are calculated in the configuration-average distorted-wave approximation. Contributions from excitation autoionization are found to be strong for each ion. When comparing theory with the recent crossed-beams measurements of Stenke et al. [J. Phys. B 28, 2711 (1995)], ionization from the ground configuration dominates for W4+ and W5+, while ionization from metastables of excited configurations dominates for W6+. copyright 1997 The American Physical Society
