【 摘 要 】

Double differential cross sections (DDCS) of vapor phase water molecules by similar velocity C6+, O8+and Si13+ion impact have been measured by the electron spectroscopy technique. The total ionization cross sections (TCS) were obtained by numerical integration of the DDCS results. All the existing data have been plotted after scaling. Gradual deviation of the TCS from the first Born predicted qp2-scaling has been observed.
