【 摘 要 】

Absolute cross sections for electron-impact ionization of Wq+ions (q ≤ 17) are measured using a well established electron-ion crossed beams technique. A special problem with many-electron tungsten ions is the existence of large numbers of long-lived excited states and their presence in the primary ion beams employed in the experiments.
