Abstract

We discuss double and single differential cross sections (DDCSs and SDCS) for secondary electron production (30-1000 eV and 20-160°) in collisions of 6.0 MeV/u O8+ ions with water vapor. All the DDCSs and SDCS were compared with previous experimental results obtained with 6.0 MeV/u C6+ ions. The DDCSs of O8+ ions showed nearly symmetric angular distributions around 90° in the energy range of 30-700 eV, which was quite consistent with those of C6+ ions, while the SDCS of O8+ ions showed about 1.7 times larger yield than that of C6+ ions, due to a greater ionizing power of high-Z projectile. Comparison with theoretical calculations using CDW-EIS is also presented at the conference.
