Abstract

Distribution of charge state for O⁵⁺ ions penetrating the H2 gas targets with a certain length and different atomicity densities was measured. Both the average charge state and the equilibrium average charge state were calculated by a computer program, and that agrees well with the experimental data. The results indicate that the electron capture cross section is increased during the collisions, and the charge state is reduced with the increasing target atomicity density. When the atomicity density reaches the order of 1014 cm^-3, there is balance between the electron capture and ionization of the incident ions, as a result, the projectile achieves the equilibrium average charge state of 1.2.
