【 摘 要 】

We have measured the electron double differential cross section (DDCS) for 3.75MeV/u O8+and O5+colliding on He atom. The projectile q-dependence on electron emission for different angles is investigated. The DDCS ratios for two charge states are found to be dependent on emission angle and energy of the electrons. A good agreement is found between the experimental data of DDCS ratios and the continuum distorted wave-eikonal initial state (CDW-EIS) predictions.
