Projectile 1s electron loss in collision systems F8++Cand O7++C

In this paper, we present our study on the K shell electron loss of hydroge n-like O and F ions by C atom in the impact energy range 20 MeV to 100 MeV. The PWBA calculations for electron loss neglecting screening by the target electrons are in good agreement with the measured cross-sections at high i mpact energy. Large deviations are seen in the measured loss cross-sections at intermediate impact energy and this is attributed to capture ionization (CI) which is important in nearly symmetric collision systems.
